When I ran .\PCbuild\amd64\python.exe -m test -v test_regrtest in Powershell on Windows 10, it showed that this test case failed with 8 failures. All cases were releted to the subprocess with the wrong encodings. Here is the output of the test case:

The reason is os.getcwd() returns result with different encoding format due to the localization of PCs. The deep solution is to modify the getcwd() function always return UTF-8 encoding format. If it is okay, I am glad to improve it.

The reason is os.getcwd() returns result with different encoding format due to the localization of PCs

getcwd() returns a Unicode string which has no encoding.

The deep solution is to modify the getcwd() function always return UTF-8 encoding format.

getcwd() is implemented with Unicode native functions on Windows.

On Windows, it's possible to create filenames and directories with names which cannot be encoded with the ANSI code page. By the way, the OEM code page used by the Windows console can be different than the ANSI code page.

No, what is needed here is just to change how cwd is formatted. Easy way, bad: use ascii() formatter. That's bad, since the console is likely able to display most non-ASCII character.

My favorite method:

>>> encoding="gbk" >>> name="hello\xe6" >>> formatted = name.encode(encoding, "backslashreplace").decode(encoding) >>> print(formatted) hello\xe6

where encoding is sys.stdout.encoding.

I wrote PR #109537 to fix your issue. Can you test it?

Thank you very much. I just cloned your code and ran the test. It showed okay with the change.

Thanks for the bug report and testing my fix. I will backport this fix with all other libregrtest changes once 3.12 branch will be unblocked after 3.12.0 final release.
