GitHub Copilot’s automatic git commit message generation feature is incredibly useful, isn’t it?
It’s a real lifesaver when you want to properly manage Git in personal development but find writing commit messages tedious.
However, you may occasionally encounter errors. In this article, I’ll share a somewhat unusual error I recently struggled with for reference.
What Happened
After staging changes and pressing the Generate button, the following error occurred:
fatal: unrecognized sequence when parsing git diff outputWhat I Tried
After researching, I found similar reports on GitHub Discussions:
I tried restarting Visual Studio, updating, clearing cache, and updating Git, but none of these resolved the issue.
Solution
In my environment, unstaging (or deleting) files with Japanese names solved the problem.
Multiple similar solutions are reported in the thread mentioned above.
Conclusion
The latest version of Visual Studio now reads Git Windows output directly, which has significantly reduced errors compared to before.
That’s exactly why this problem was quite puzzling, but if you encounter the same error in a Japanese environment, first try temporarily removing Japanese filenames.
This solution may also apply to problems caused by filenames in other languages.
