[issue9820] Windows : os.listdir(b'.') doesn't raise an error for unencodable filenames

To avoid the error, a solution is to support the PEP 383 on Windows (for the mbcs encoding). I opened a separated issue for that: #9821.

But support PEP 383 will not fix this issue because the current implementation of listdir(b'.') doesn't use the Python codec, but use raw bytes filenames (use the ANSI API).
