> Please see the discussion on https://bugs.python.org/issue43552: locale.getpreferredencoding() needs to be deprecated as well. Instead we should have a single locale.getencoding() as outlined there... perhaps in a separate ticket ?! Thanks.

Yeah, I read this issue. But these things are too complicated :-) I prefer to move step by step.

Once locale.getencoding() (or a similar function) is added, we can update the deprecation message.

I hope to be able to deprecate getdefaultlocale() and to add such new function in Python 3.11.
