…patterns FileList matched MANIFEST.in patterns against on-disk names byte-for-byte with no Unicode normalization. On macOS APFS/HFS+, a file stored NFD and a pattern authored NFC denote the same file but differ byte-for-byte, so an exclude/global-exclude/recursive-exclude/prune rule could silently fail to drop a non-ASCII-named file, publishing it in the sdist despite the rule. Normalize both the pattern and the candidate path to NFC before matching, via a new unicode_utils.normalize() helper and a _NormalizedMatcher wrapper around the compiled pattern in translate_pattern. Fixes GHSA-h35f-9h28-mq5c. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> (cherry picked from commit dd9f436) Backported unchanged from v83.0.0 onto v82.0.1; the fix uses no Python 3.10+ features, so 82.0.1.x keeps supporting Python 3.9.

Bump version to 82.0.1.post1 (PEP 440 post-release) and record the backported GHSA-h35f-9h28-mq5c fix in NEWS.rst. Python 3.9 support is unchanged (requires-python >= 3.9). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
