How to Internationalize Software: A Guide for Developers

The Importance of Software Internationalization

Internationalization (often abbreviated as i18n) is the process of designing and developing software so that it can be easily adapted to various languages and regions without requiring engineering changes. If you’re wondering how to internationalize software, it involves ensuring that your product’s architecture supports localization efforts right from the start. This is a crucial step in expanding a software product’s reach to a global audience. By internationalizing software, you make it easier to localize later, meaning you can adapt it for specific languages or regions with minimal effort. Localization includes tasks like translating text, formatting dates and numbers according to local conventions, and incorporating culturally relevant images and references.

Why is software internationalization so important?

• Market expansion and revenue growth: Internationalization automatically expands the market for your product. As many computer firms obtain around half of their revenue from outside the United States, internationalization offers a significant opportunity for revenue growth.
• Competitive advantage: In today’s interconnected world, users expect software to be available in their native languages. Internationalized software has a significant advantage over software that only supports a single language.
• Reduced time and cost: While localization does require an investment, internationalization makes the process much more efficient. By designing software with internationalization in mind, you can avoid costly and time-consuming rewrites later on.
• Meeting global demand: The global internet demands software that can be localized for multiple countries and regions.

The Solaris operating system, for example, is internationalized, providing the infrastructure and interfaces needed to create internationalized software. This means that software developers can create applications that are compatible with all the languages and cultures supported by Solaris.

How to Internationalize Software in 10 Steps

Learning how to internationalize software is essential for expanding its reach to a global audience. To help you through this process, here’s a comprehensive 10-step plan that breaks down each phase and highlights the importance of every step along the way.

1. Plan for Internationalization from the Start

Integrating internationalization into the initial design and development process, rather than treating it as an afterthought, is more efficient and saves time and resources. This is because retroactively adapting software for various languages and cultures often necessitates significant code changes, which can be time-consuming and expensive. Conversely, considering internationalization from the outset allows developers to create a flexible and adaptable software foundation.

For instance, using Unicode for character encoding from the beginning eliminates the need for code revisions later to support different writing systems. Similarly, externalizing user interface text from the start makes translation a smoother process and avoids the need to search for and modify hardcoded text scattered throughout the codebase.

Starting with an internationally-minded design strategy is key when considering how to internationalize software effectively. By incorporating internationalization from the outset, software can be localized, or adapted to specific languages or regions, with minimal effort. This approach not only broadens the product’s potential market but also speeds up the localization process. On the other hand, neglecting to plan for internationalization can result in time-consuming re-releases to address issues that arise during translation and adaptation.

2. Choose a Suitable Software Architecture

When designing software for a global audience, choosing a suitable software architecture is crucial. A modular architecture, where language and culture-dependent components are separated from the core logic, is extremely beneficial for internationalization.This approach makes it easier to adapt the software to various locales without modifying the core functionality.

Let’s break down why this is so important:

• Simplified localization: With a modular design, translators and localizers can focus solely on the language and culture-specific components, such as user interface text, date and time formats, and currency symbols, without affecting the application’s core code. This separation simplifies the localization process, making it faster and more cost-effective.
• Reduced risk of errors: Modifying core code always carries a risk of introducing bugs. By separating localizable elements, developers can minimize changes to the core logic during localization, reducing the likelihood of introducing errors.
• Improved maintainability: When updates or bug fixes are needed, developers can modify the core application without affecting the localized components. This separation simplifies maintenance and ensures that translations remain consistent across different software versions.
• Enhanced flexibility and scalability: A modular architecture makes it easier to add support for new languages and regions in the future. New locale-specific modules can be developed and integrated without impacting existing components.

Consider a scenario where an application needs to be localized for different regions that use different date formats. With a modular architecture, the date formatting functionality can be isolated into a separate module. This module can then be easily swapped or modified to adhere to the specific date format of each target region without affecting other parts of the application.

Internationalization is easier when you build with a modular architecture. This approach allows developers to create adaptable software that can be easily localized for different markets. It streamlines the process and helps teams expand their reach globally.

3. Handle Character Encoding with Unicode

To effectively handle diverse writing systems and characters in software development for a global audience, implementing Unicode support is not just recommended, it’s essential for ensuring global compatibility and a seamless user experience. Unicode is a character encoding standard that assigns a unique code point to every character, regardless of the language, script, or platform.

Before Unicode was widely adopted, software developers often relied on character encodings specific to particular languages or regions. For example, ASCII, a 7-bit encoding, was widely used for English and a few other Western European languages, but it couldn’t handle characters from many other writing systems. This reliance on localized encodings led to compatibility problems when software was used with different languages or on systems with varying encoding standards.

Unicode solves this problem by providing a single, universal standard for representing characters from all major writing systems. Understanding how to internationalize software is crucial, and Unicode plays a key role by ensuring that text is correctly displayed and processed, no matter the user’s language or location. This universality is a cornerstone of software internationalization, enabling seamless communication across global markets.

Consider a database application that stores user information, including names. If this application uses a character encoding limited to a specific language, users with names containing characters outside that encoding will encounter problems. For instance, storing the German name “Jürgen” in an ASCII database would likely result in data loss or corruption, as ASCII lacks the “ü” character.

By implementing Unicode, you avoid these issues and ensure that your software can:

• Store and display text: Accurately represent characters from a wide range of languages, including those with complex scripts like Chinese, Japanese, and Korean.
• Process text: Enable string operations, such as comparison and sorting, to function correctly for all supported languages. SunOS, for example, uses the Extended Unix Code (EUC) encoding scheme to support multibyte characters required by East Asian languages.
• Maintain data integrity: Prevent data loss or corruption when handling text from multiple languages.

Unicode is supported by a variety of encoding forms, including UTF-8, UTF-16, and UTF-32, each with its own characteristics. For instance, UTF-8 is a variable-length encoding that is backward compatible with ASCII, making it a popular choice for web applications8. UTF-16 uses 16-bit code units and is often used in Java applications.

When choosing a Unicode Transformation Format (UTF) for your software, it’s important to consider factors such as:

• Data storage requirements: UTF-8 is generally more space-efficient for text containing mostly ASCII characters, while UTF-16 may be more efficient for Asian character sets.
• Programming language and platform: Some programming languages or platforms have a preference or better support for certain UTFs. For instance, Java uses UTF-16 internally, while DB2 for z/OS uses UTF-8 to store catalog data.
• Performance: Processing efficiency can vary slightly between UTFs depending on the characters being handled and the specific operations performed.

In conclusion, adopting Unicode for character encoding is a fundamental step when internationalizing software. It ensures that your software can handle the complexities of global communication while delivering a consistent, high-quality user experience to a diverse audience. By grasping the importance of Unicode and selecting the appropriate UTF for your specific needs, you lay the groundwork for creating truly global software.

4. Externalize User Interface Text

Storing all user-facing text, including labels, messages, and help content, in external resource files instead of embedding it directly in the source code is a fundamental principle of software internationalization. This practice is crucial for simplifying translation and facilitating easier updates without requiring modifications to the source code.

Benefits of externalizing text

• Streamlined translation: When user interface text is stored externally, it can be easily extracted and sent to translators without the need to sift through complex source code. This separation simplifies the language translation process and reduces the risk of errors. Translators can focus solely on the text itself, without being burdened by code syntax or logic.
• Efficient updates: If text changes are required, for example, due to bug fixes, feature updates, or rebranding, modifications can be made directly to the external resource files without altering the source code. This approach saves development time and effort, as it eliminates the need for recompilation or extensive code changes.
• Simplified locale management: External resource files can be organized by locale, making it easy to load the appropriate language version at runtime based on the user’s preferences. Under the SunOS system, for instance, system messages reside in directories structured by language and domain, such as /usr/lib/locale/language/LC_MESSAGES/domain.mo. This directory structure highlights how externalizing text facilitates loading the correct localized resources.
• Reduced file sizes: In some cases, storing text externally can lead to smaller executable file sizes, as the text itself is not embedded in the binary. This can be beneficial for applications with large amounts of user interface text.

Tools and Techniques for Externalizing Text

Various tools and techniques are available to facilitate text externalization, including:

• gettext: This widely used tool, part of the GNU gettext family of tools, provides a framework for extracting translatable strings from source code and creating message catalogs that can be easily translated. We would like to highlight that gettext is recommended for applications in the Solaris environment. They offer numerous examples demonstrating its usage, including extracting strings, creating message catalogs, and integrating them into applications.
• Resource bundles: Some programming languages and frameworks, such as Java, provide built-in mechanisms for handling externalized text through resource bundles. Developers can create locale-specific resource files containing key-value pairs, where the keys represent the text identifiers, and the values hold the corresponding translated strings.
• XML-based files: Extensible Markup Language (XML) files offer a structured approach to storing user interface text. Each text string can be encapsulated within XML tags, making it easily parsable by the application at runtime.

Best Practices for Externalizing Text

• Choose meaningful keys: When using key-value pairs to store externalized text, use descriptive and unique keys that clearly identify the corresponding text strings. This makes the resource files easier to understand and maintain.
• Provide context for translators: Include comments or additional context information within the resource files to help translators understand the meaning and purpose of each text string.
• Test thoroughly: After integrating externalized text, conduct comprehensive testing to ensure that the correct language versions are loaded and displayed properly in the application’s user interface.

When developers externalize user interface text, they make software much more adaptable for localization, which is key when internationalizing software. This approach not only makes translating easier but also simplifies future updates, allowing software to quickly meet the needs of a global audience. In the end, it leads to a smoother, more user-friendly experience for people, no matter where they are or what language they speak.

5. Implement Locale-Aware Formatting

The fifth step, implementing locale-aware formatting, is a critical aspect of internationalizing software. Numbers, dates, times, and currencies are presented in various formats across the globe. To ensure your application displays these values correctly based on the user’s region and language settings, you must utilize locale-aware formatting functions. Failing to do so can lead to misinterpretations and a poor user experience. For instance, a date format of “10/7/89” could be interpreted as October 7th, 1989 in the US but as July 10th, 1989 in the UK.

Here are several examples of locale-aware formatting techniques:

• strftime() function: This function allows you to format dates and times according to the conventions of the user’s locale. You provide a format string with specific conversion specifiers, and the function replaces those specifiers with the corresponding localized values.
• strfmon() function: This function is specifically designed for formatting monetary values based on locale settings. You can control aspects such as currency symbol placement, negative sign representation, and digit grouping.
• localeconv() function: For more granular control over numeric and monetary formatting, you can utilize localeconv(). This function populates a structure with various formatting details derived from the current locale, including the radix character, thousands separator, currency symbol, and digit grouping rules. While this function provides the raw data, you are responsible for interpreting this information and applying it to your formatting logic.
• Locale-specific databases: It’s possible to use a “language information database” (langinfo), which stores cultural data for various locales. This database contains information relevant to formatting, such as date and time formats, currency symbols, and numeric conventions. Functions like nl_langinfo() can be used to retrieve specific pieces of information from this database.

The importance of locale-aware formatting extends beyond dates, times, and currencies.

• Number formatting: Consider a scenario where an application needs to display large numbers. In some locales, a comma separates thousands, while in others, a period is used. A locale-aware system would automatically adjust the number formatting based on the user’s settings.

Adding locale-aware formatting to your app makes it more intuitive and welcoming for users around the world. When people see information in a way that feels familiar, they’re more likely to stay engaged and have a better overall experience.

6. Address Cultural Differences

When internationalizing software, considering cultural nuances that go beyond mere language translation is extremely important. To ensure a truly global user experience, it’s essential to adapt not only the language but also graphics, icons, colors, and symbols. This approach helps avoid misinterpretations and ensures your software resonates with individuals from diverse cultural backgrounds.

• Graphics and icons: A mailbox is a good example to illustrate how a symbol that’s common in one culture might be meaningless in another. A mailbox icon, while instantly recognizable to a US audience, might not hold the same significance for users in regions where mailboxes are uncommon or visually distinct. When choosing graphics and icons, aim for universally understood concepts or use visuals that are relevant to the target culture.
• Colors: Color symbolism varies significantly across cultures. A color that represents positivity in one culture might be associated with mourning or negativity in another. It’s essential to research color associations in the target culture to ensure that the chosen color scheme conveys the intended message.
• Symbols: Similar to colors, symbols can hold different meanings depending on cultural context. Certain hand gestures, religious symbols, or even seemingly innocuous icons can be interpreted negatively or offensively in some cultures. Thorough research and sensitivity to cultural norms are paramount when incorporating symbols into your software’s design.

Cultural Considerations in User Interface Design

• Date and time formatting: As discussed in the previous step on locale-aware formatting, the way dates and times are displayed varies widely across different regions. When internationalizing software, it’s crucial to ensure that your application adheres to the conventions of each target locale. This includes considering factors such as date ordering (day/month/year or month/day/year) and the choice between 12-hour or 24-hour time formats. Properly adapting these elements ensures a seamless user experience across diverse global markets.
• Reading direction: Not all languages are read from left to right. Right-to-left languages, such as Arabic and Hebrew, require a user interface layout that accommodates this difference. This includes mirroring the layout, aligning text appropriately, and ensuring that elements like scrollbars and progress bars function intuitively.
• Cultural sensitivities: Be mindful of cultural sensitivities when selecting imagery, icons, and language. Avoid content that could be considered offensive, disrespectful, or inappropriate in the target culture. For instance, depictions of certain animals, religious figures, or historical events might be taboo in some regions.

To create software that truly connects with users from different backgrounds, it’s crucial to address cultural nuances. An essential aspect of internationalizing software is understanding these cultural differences and integrating them into the design process. A culturally aware approach to software design not only fosters inclusivity but also improves user satisfaction and can significantly contribute to the overall success of your product in the global market.

7. Test for Internationalization and Localization

Thoroughly testing your software in different target locales is essential to ensure a seamless user experience across all supported regions. This process, encompassing language, date/time formats, currency display, and input methods, validates that your internationalization and localization efforts have been successful.

• Language: Verify that all text within the application is displayed correctly in the target language, including menus, dialog boxes, error messages, and help content. This testing should encompass not only the accuracy of the translations but also aspects such as text expansion, which can affect the layout and usability of the user interface. We would like to emphasize the importance of using the correct character encoding for different languages to avoid display issues. For instance, Asian languages often require multibyte character sets like Extended Unix Code (EUC).
• Date/time formats: Ensure that dates and times are formatted correctly based on the conventions of the target locale. This includes factors such as date ordering (e.g., day/month/year vs. month/day/year), the use of 12-hour or 24-hour time formats, and the display of weekdays and month names in the appropriate language. It’s important to highlight the strftime() function as a key tool for formatting dates and times according to locale-specific rules.
• Currency display: Verify that currency symbols, decimal separators, and digit grouping are displayed correctly for the target locale. For example, the Euro symbol (€) should be used for locales where the Euro is the official currency, and the decimal separator should be a comma (,) in some locales and a period (.) in others. The localeconv() function can be used to obtain locale-specific details for formatting monetary values. Additionally, applications can access a language information database (langinfo) to retrieve cultural data relevant to formatting, including currency symbols and numeric conventions.
• Input methods: When internationalizing software, it’s vital to make sure users can enter text and data using input methods that fit their local needs. This becomes especially important for languages with character sets that are very different from English, like those using non-Latin scripts. Features like “dead keys” and “compose sequences” play a crucial role in supporting different keyboard layouts, allowing software to be easily used across various languages and regions.

Testing Methodology

• Real devices and emulators: Conduct testing on real devices running the target locale’s operating system and language settings whenever possible. If real devices are not available, utilize emulators or virtual machines to create a representative testing environment.
• Locale switching: Test the application’s ability to switch seamlessly between different locales at runtime. This ensures that the correct language and formatting rules are applied dynamically based on the user’s preferences.
• Pseudo-localization: Use pseudo-localization techniques, such as replacing characters with visually similar ones or adding padding to text strings, to simulate the effects of language expansion and identify potential layout issues early in the development process.
• User acceptance testing: Involve native speakers of the target language in the testing process to get feedback on the accuracy, clarity, and cultural appropriateness of the localized user interface.

Thorough testing for internationalization and localization is an ongoing process that should be integrated into every stage of software development, especially when you’re learning how to internationalize software effectively. By dedicating time and resources to this crucial aspect, you ensure that your product can seamlessly adapt to various languages, cultures, and regions. This proactive approach not only enhances your product’s global appeal but also helps deliver a positive user experience to customers worldwide.

8. Provide Clear and Translatable User Messages

Now it’s time to focus on a critical aspect of user experience—how your software communicates with its users. As part of the process of internationalizing software, user messages must be easily understood and adaptable for different languages and cultures. These messages encompass a broad range of text elements, including:

• Menus and dialog boxes: These guide users through the application’s features and options.
• Error messages: These provide feedback when something goes wrong, ideally with actionable insights on how to resolve the issue.
• Help content: This provides users with information about the application’s functionality and how to use it effectively.
• Tooltips and instructions: These offer concise guidance on specific features or actions.

Designing user messages for translatability and cultural appropriateness requires a thoughtful approach:

• Avoid technical jargon and slang: Technical terms, abbreviations, and informal language can be difficult to translate accurately and are likely to be unfamiliar to users from different technical backgrounds or cultures. Therefore, avoiding jargon, abbreviations, and acronyms in user messages is highly recommended.
• Use simple sentence structures: Long, complex sentences with multiple clauses can be challenging to translate and understand, especially for users who are not native speakers of the target language. Opt for clear, concise language and short sentences whenever possible. It’s important that you “write out whole messages” to avoid ambiguity.
• Be mindful of word order: Word order varies significantly between languages, which is crucial when internationalizing software. Avoid creating messages where the meaning depends on a specific word order, as this can lead to mistranslations. Experts caution against making assumptions about word order in strings and emphasize the challenges of translating “compound messages,” where meaning is conveyed through the arrangement of multiple parts. When internationalizing software, it’s essential to design messages that can adapt seamlessly to different linguistic structures.
• Consider cultural context: Humor, idioms, and cultural references often do not translate well and can lead to misunderstandings or even offense. What might seem like a harmless joke or reference in one culture could be perceived as inappropriate or insensitive in another.

Here some specific guidance on handling user messages in the context of internationalization:

• Externalize messages: Store user messages outside of the application’s source code. This separation makes it easier to translate messages without modifying the application’s core logic.
• Use message catalogs: Message catalogs (or databases) are a common approach to managing translated user messages. Message catalogs store translations for each supported locale, and the application dynamically loads the appropriate translations based on the user’s language settings. It’s important to note that this approach is essential for creating easily localized software.
• Employ message handling functions: Functions like gettext() and catgets() are specifically designed for retrieving translated messages from message catalogs. By wrapping user-facing strings in these functions, you ensure that the application displays the correct translation based on the user’s locale.
• Test with native speakers: Engage native speakers of the target language to review translated messages for accuracy, clarity, and cultural appropriateness. They can identify potential issues that might be missed by automated translation tools or non-native speakers.

By following these guidelines, you can create user messages that are clear, concise, and easily translatable, which is crucial when internationalizing software. This approach will not only enhance the overall user experience but also ensure your software is adaptable and accessible to a global audience.

9. Document Internationalization and Localization Processes

Creating comprehensive documentation of your internationalization and localization processes is crucial for maintaining consistency, streamlining workflows, and facilitating effective collaboration with translators and localizers. This documentation serves as a central repository of knowledge and guidelines, ensuring that everyone involved in the globalization of your software knows how to internationalize software effectively. By clearly outlining best practices and processes, you ensure a smooth and efficient transition as you adapt your software for global markets, empowering your team to navigate the complexities of internationalization with ease.

Here are some valuable insights into the key elements that such documentation should encompass:

File Formats and Coding Conventions

• Character encoding: Specify the character encoding (e.g., UTF-8, ISO 8859-1) used for source code files, resource files, and any other text-based assets. Consistent use of the appropriate encoding is essential to avoid character corruption and display issues. Understanding and correctly handling different character encodings for internationalization, particularly in the context of Asian languages and multibyte character sets, is extremely important.
• Message catalog format: If you’re using message catalogs to manage translated user messages, document the format of these catalogs. This includes details such as:
  • File extension (e.g., .po, .cat)
  • Syntax for defining messages and message sets
  • Use of comments and metadata
  • Escape sequences and special characters
• Coding standards for internationalization: Establish coding conventions that promote internationalization. This might include:
  • Using message handling functions (e.g., gettext(), catgets()) to wrap all user-facing strings. These functions are crucial for retrieving translated messages from catalogs.
  • Avoiding hardcoded strings and magic numbers in the application’s core logic.
  • Using locale-aware functions for formatting dates, times, currency, and numbers. Key tools for this purpose are functions like strftime() and localeconv().
  • Parameterizing code to handle variations in string length, text direction, and other locale-specific factors is a crucial step in internationalizing software. It’s important to accommodate these variations, especially when dealing with translated text, which can expand or contract significantly compared to the original language. By accounting for these differences, developers can ensure that their software functions seamlessly across different languages and regions.

Translation Guidelines

• Style and tone: Provide translators with clear guidance on the desired style and tone of the translated text. Specify whether the language should be formal or informal, technical or user-friendly. Use clear, concise language and avoid technical jargon in user messages.
• Contextual information: Offer translators as much context as possible for each message or text string. This might include:
  • Screenshots or mockups of the user interface
  • Descriptions of the target audience
  • Explanation of the application’s functionality
  • Links to relevant documentation or resources
• Glossary of terms: Create a glossary of terms specific to your application or industry, providing translations for each term. This helps ensure consistency and accuracy in the translated text.
• Cultural considerations: Provide translators with information about cultural sensitivities and nuances relevant to the target locale. This might include:
  • Guidance on appropriate imagery and symbolism
  • Explanation of taboos or sensitive topics
  • Examples of culturally appropriate language and phrasing

Localization Process

• Workflow and tools: Document the steps involved in the localization process, from preparing translatable files to integrating localized content into the application. Specify the tools used for translation, version control, and quality assurance.
• Roles and responsibilities: Clearly define the roles and responsibilities of everyone involved in the localization process, including developers, translators, reviewers, and testers.
• Testing procedures: Outline the procedures for testing localized versions of the application, encompassing language accuracy, functionality, and cultural appropriateness.

Creating and maintaining detailed documentation for your internationalization and localization processes is the first step toward successfully globalizing your software. With this solid foundation in place, you pave the way for crafting high-quality, adaptable software that can seamlessly thrive in a variety of markets around the world.
