New submission from STINNER Victor <victor.stin...@haypocalc.com>: PyUnicode_EncodeFSDefault() and os.fsencode() should decompose the filename (NFD) before encoding it to utf-8.
PyUnicode_DecodeFSDefault(AndSize)() and os.fsdecode() should precompose the filename (NFC) after decoding it from utf-8. Qt library does this on Mac: see locale_encode()/locale_decode() (filename encoder/decoder) functions in src/corelib/io/qfile.cpp. It should fix some issues of test_pep277 on Mac OS X (see #8423). I'm not completly sure that we should do that :-) (I used the nosy list from issues #4388 and #8423). -- Technical Q&A QA1173, Text Encodings in VFS: http://developer.apple.com/mac/library/qa/qa2001/qa1173.html Q: I'm writing a file system (VFS) plug-in for Mac OS X. How do I handle text encodings correctly? A: In Mac OS X's VFS API file names are, by definition, canonically decomposed Unicode, encoded using UTF-8. This raises a number of interesting issues.
