Worked on the MuseScore repository to address a persistent issue with symbol formatting during text editing, focusing on improving the reliability of pasting special musical symbols. Using C++ and leveraging the TextBase editing pipeline, implemented a targeted bug fix that ensures symbol formatting and cursor placement are preserved when users paste modified-sized symbols. The solution involved explicitly storing formatting in the edit text object before insertion, allowing correct formatting to persist through paste and insertion operations. This work reduced manual reformatting for users, enhanced the stability of symbol handling, and lowered support overhead, demonstrating strong skills in bug fixing and text editing.
