I don't know the right name of this document.

If you use ignore or replace, filenames will be valid unicode strings, but you will be unable to open / copy / remove you file. > > Default encoding > > ================ > > > > Python uses "UTF-8" as the default Unicode encoding.

Yes, we might remove sys.getdefaultencoding() and write that PyUnicode_FromStringAndSize() uses the UTF-8 charset. > sys.setdefaultencoding() should probably be dropped altogether from > Python3.
