[issue10209] Mac OS X: Decompose filenames on encode, and precompose filenames on decode

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

I'd like to see this patch reverted. I don't think it is useful.

1. encoding with NFD should not be necessary, as the system will do that, anyway.
2. decoding with NFC is incompatible with previous Python releases, and I can't see why NFC is conceptually better than NFD.

To give an analogy: if we have a case-insensitive file system, we don't normalize into lower-case, either, do we?
