Michele Orrù <maker...@gmail.com> added the comment:
unittest.skip* are decorators, so useless in this case; also, AFAIS
Lib/test/ uses sys.platform.
I would suggest to put a try statement in encodings.mbcs, and raise an
error in case the imported modules imported are not found.
But this is another story.
