Worked on moltbot/moltbot to address a text rendering issue in the TUI for CJK languages, focusing on improving the user experience for long-form CJK content. Used TypeScript and front end development skills to fix a bug that caused unwanted spaces to appear in CJK text, reducing UI misrendering and potential support issues. The solution involved isolating the fix to the sanitization path and expanding test coverage to ensure text integrity and prevent visual artifacts. Added comprehensive tests to validate that the sanitizer preserves CJK prose, enhancing regression safety and maintaining code quality throughout the update process.
