Worked on refining the Chinese localization for the Sandboxie UI in the sandboxie-plus/Sandboxie repository, focusing on improving translation accuracy and completeness. Addressed incorrect translations in the sandman_zh_CN.ts file by removing the 'unfinished' tag and ensuring all strings were properly localized, which enhanced the user experience for Chinese-speaking users. Utilized TypeScript and localization best practices to validate end-to-end UI rendering, confirming that updates were reflected accurately throughout the interface. Documented the translation workflow and prepared release notes to support future localization efforts. The work concentrated on bug fixing rather than feature development, demonstrating attention to detail in language support.
