[issue26227] Windows: socket.gethostbyaddr(name) fails for non-ASCII hostname

[Steve Dower]

Steve Dower <steve.dower at python.org> added the comment:

Looks like what was actually applied was changed to PyUnicode_DecodeFSDefault, which was later changed on Windows to be always UTF-8.

They'll need to be normalised throughout Modules/socketmodule.c (I can't tell at a quick glance which need updating). We should also figure out some kind of test that can catch this sort of issue.

Sorry for guiding you wrong a few years ago, Victor!
