Worked on moltbot/moltbot to improve Unicode reliability in message previews and IRC message processing, focusing on robust handling of UTF-16 surrogate pairs. Addressed issues where message truncation or chunking could split surrogate pairs, leading to garbled notifications or malformed outbound messages. Implemented surrogate-safe truncation and chunking utilities in TypeScript, centralizing logic to prevent lone surrogates and adding comprehensive regression and socket-level tests. Refactored code for maintainability and collaborated on edge-case handling, ensuring that both direct messages and channel notifications preserved emoji and complex characters. The work emphasized full stack development and rigorous testing to enhance user experience and trust.
