Worked on the langgenius/dify repository to improve cross-platform reliability in DOCX file processing. Addressed a bug where Windows-exported DOCX files, such as those from Evernote, failed to import correctly on Linux and macOS due to differing path separators within ZIP entries. Developed a normalization function in Python to standardize backslash path separators, ensuring consistent file handling across operating systems. Added comprehensive unit tests to validate the solution and integrated these tests to support continuous integration workflows. Focused on back-end development and robust file handling, the work enhanced the repository’s ability to process DOCX files reliably in diverse environments.
