Sure, I just don't know a 'functional' enough approach to check it, like I've done it for text copy/paste.
If you mean checking the normalization macOS APIs use when returning filenames, it definitely not NFC. At least, after I rename a file using Finder, its filename is returned in NFD (decomposed) form by both file access APIs (e.g. `readdir` from C library or `NSFileManager` from Foundation framework) and when read from clipboard (for `NSFilenamesPboardType` data type).
