Worked on improving documentation export reliability in the cryptomator/cryptomator repository by addressing Unicode character rendering issues in RTF files generated by the ReadmeGenerator. Focused on correcting the Unicode escaping logic to ensure accurate display of characters across both standard and extended Unicode ranges. Enhanced the generator’s implementation in Java and expanded unit tests to cover a variety of Unicode scenarios, reducing the risk of future regressions. This work did not introduce new features but targeted a persistent bug, resulting in more robust RTF formatting and improved user experience for exported documentation. Emphasized correctness and maintainability throughout the process.
