Humble thoughts...
Is it possible a conversion from bytes (ANSI) to unicode fails on
windows? If not, is it allowed to convert to unicode with
PyUnicode_FSDecoder if function doesn't return str? For example, 
os.stat() takes str as arguments but doesn't return str.

# I noticed win_readlink() in Modules/posixmodule.c already unicode
# only. Maybe not so much problem? ;-)
