Description: Summary Fixes #2064 The packed-refs file can contain ref names that are not valid UTF-8 (e.g., Latin-1 encoded tag names created by older Git versions or systems with different locale settings). Previously, GitPython would fail with UnicodeDecodeError when reading such files. Reproduction As described in #2064: git clone https://github.com/ACRA/acra cd acra python -c 'import git; print(git.Repo(".").tags)' Before fix: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 6216: invalid continuation byte After fix: Successfully reads all 101 tags. Changes Add errors='surrogateescape' to the open() call in _iter_packed_refs() This allows reading files with arbitrary byte sequences while preserving valid UTF-8 as text Add test that verifies non-UTF8 packed-refs can be read successfully Technical Details The surrogateescape error handler is Python's standard approach for handling potentially non-UTF8 data in filesystem operations. It: Passes through valid UTF-8 unchanged Converts invalid byte sequences to Unicode surrogate characters (\uDC80-\uDCFF) Preserves the original bytes in a reversible way (can be re-encoded back to original bytes) This is the same approach used by Python's os.fsdecode() and is recommended for filesystem operations where encoding may be unknown or mixed.
