Vital Things About Software Internationalization And Localization

Posted by Chloe G. on June 27, 2023.

Software companies are presented with immense opportunities to tap into new markets and engage a diverse international audience. To seize these opportunities effectively, software internationalization and localization have become indispensable strategies. While the terms may sound similar, they represent distinct processes that empower software to adapt and flourish in global markets. 

In this in-depth blog post, we will delve into the nuances between software internationalization and localization, uncovering their meanings and the profound impact they have on the ever-expanding global software landscape.

The Difference Between Software Internationalization And Localization

Software internationalization and localization are both important processes in adapting software for global markets, but they serve different purposes. Here’s the difference between the two:

Internationalization (i18n): Internationalization refers to designing and developing software in a way that makes it adaptable to different languages, cultures, and regions without requiring significant code changes. The goal of internationalization is to create a software framework that can be easily localized for different target markets. It involves separating the software’s core functionality from its user interface and making it language-neutral, date and time format-neutral, and culturally aware. This includes considerations such as:

  • Designing the user interface to accommodate text expansion or contraction.
  • Using Unicode or other character encoding schemes to support different languages and scripts.
  • Ensuring proper handling of dates, times, numbers, and currency formats based on regional conventions.
  • Externalizing translatable strings, labels, and messages into resource files or databases.
  • Adhering to international standards and best practices.

In essence, internationalization focuses on making the software adaptable to different locales and languages, laying the foundation for localization.

Localization (l10n): Localization is the process of adapting software to a specific locale or target market, making it linguistically and culturally appropriate for users in that region. It involves translating the user interface, documentation, and other relevant content into the target language(s) while considering local conventions, preferences, and norms. Key aspects of localization include:

  • Translating all visible text, such as menus, buttons, and labels, into the target language.
  • Adapting date and time formats, number formats, and currency symbols to align with local conventions.
  • Adjusting images, graphics, and multimedia content to suit the target culture.
  • Considering local legal requirements, units of measurement, and regulatory standards.
  • Ensuring the software functions correctly in the target locale, taking into account differences in character sets, sorting orders, and user input methods.

Localization is a more specific and detailed process compared to internationalization. It tailors the software to a particular language and cultural context, providing a user experience that feels native to the target audience.

Internationalization is the process of designing software to be easily adaptable for different languages and regions, while localization involves customizing the software for a specific locale, translating content, and aligning it with local preferences and conventions.


How to Internationalize Your Software

  • Unicode Support: Ensure that your software supports the Unicode character encoding standard, which provides a comprehensive set of characters covering multiple languages and scripts. By adopting Unicode, your software becomes capable of displaying and handling a vast array of languages and characters.
  • Externalize Localizable Content: Separate the user interface elements, such as text strings, error messages, and labels, from the software’s core code. This separation allows for easy translation and adaptation to different languages without modifying the software’s underlying functionality.
  • Date, Time, and Number Formats: Implement flexible formatting options that can accommodate different date, time, and number formats prevalent in various regions. This ensures that the software can seamlessly present information in formats familiar to the target audience.
  • Support for Multiple Character Encodings: Extend support for various character encodings to cater to languages that may require different encoding schemes. This enables the software to handle different writing systems and character representations effectively.
  • Layout and UI Adaptability: Design the software’s user interface (UI) in a way that accommodates varying text lengths and directionality (e.g., left-to-right and right-to-left) for different languages. This includes considering the space required for translations and ensuring that UI elements dynamically adjust to fit localized content.

How to Localize Your Software

  • Language Translation: Engage professional translators or translation services to accurately translate all user-facing content, including menus, buttons, error messages, and documentation, into the target language(s). Linguistic accuracy, cultural context, and idiomatic expressions should be considered during the translation process.
  • Cultural Adaptation: Modify the software’s visuals, icons, colors, and symbols to align with the cultural preferences and norms of the target audience. This includes adapting graphics and imagery to reflect local customs and ensuring that visual elements are culturally appropriate.
  • Regional Preferences: Adjust the software’s functionality, features, and content to cater to specific regional requirements, such as measurement units, currency formats, and local regulations. Adapting the software to regional preferences enhances usability and ensures compliance with local standards.
  • Testing and Quality Assurance: Conduct thorough testing to ensure that the localized software functions seamlessly and accurately reflects the intended user experience. This includes verifying the accuracy of translations, checking for any layout or formatting issues, and validating the software’s compatibility with the targeted locale.
