Worked on the open-telemetry/opentelemetry-collector-contrib repository to enhance text processing reliability in backend systems using Go. Developed UTF-8-safe truncation for the truncate_all function, addressing the risk of invalid UTF-8 outputs and ensuring string integrity when truncating user-facing text. Introduced an optional parameter to maintain backward compatibility with previous byte-level truncation, minimizing disruption for existing users. Created comprehensive tests covering rune boundaries and grapheme clusters to validate the new behavior, while preserving existing test coverage. Updated documentation to clarify truncation limits and UTF-8 handling, linking changes to relevant tracking issues. Focused on backend development and robust data handling.
