Worked on enhancing localization for the CombatExtended-Continued/CombatExtended repository by delivering updated and refined Simplified Chinese translations over a two-month period. Focused on internationalization and localization, the work involved updating XML-based translation resources to align with the latest game version, completing missing content, and removing redundant entries to streamline maintenance. Conducted localization quality assurance to validate string context, encoding, and UI integration, ensuring accurate display for Chinese-speaking users. These efforts improved accessibility and user experience, positioned the product for targeted market expansion, and established a more maintainable localization workflow without introducing new bugs or regressions during the update process.
