Worked on localization and internationalization for the sandboxie-plus/Sandboxie repository, focusing on improving the quality and consistency of Chinese translations across Sandboxie Plus and Sandman components. Used TypeScript to standardize UI strings, error messages, and settings descriptions, ensuring clear and consistent terminology between zh_CN and zh_TW locales. Delivered a targeted fix to resolve a URL encoding issue in the Patreon supporter certificate message, addressing a navigation problem for Chinese users. Contributed multiple translation updates and a minor UI adjustment to enhance discoverability of the 'Test Settings...' button, emphasizing reliability and maintainability in localized user experiences throughout the project.
