Worked on expanding translator language support in the koreader/koreader repository, focusing on internationalization and localization improvements. Enhanced the translator module by adding a wide range of new language codes and display names, with particular attention to accurate mapping for Filipino and consistent representation of traditional Chinese throughout the user interface. Utilized Lua to implement these changes, ensuring that language data was both comprehensive and correctly labeled. The work addressed edge-case translation issues and improved the overall quality of localization data. This targeted feature development contributed to a more robust multilingual experience for users, though no bug fixes were recorded during the period.
