That other PEP being PEP 302. That said, Unicode strings *are* permitted on sys.path - the import system will automatically encode them to an 8-bit string using the default filesystem encoding as part of the import process. This works fine on Unix systems that use UTF-8 encoded strings to handle Unicode paths at the C API level, but is screwed on Windows because the default mbcs filesystem encoding can't handle the full range of possible Unicode path names (such as the Chinese directories that originally gave Kristján grief). To get Unicode path names to work on Windows, you have to use the Windows-specific wide character API instead of the normal C API, and the import machinery doesn't do that. So this is taking something that *already works properly on POSIX systems* and making it work on Windows as well. >> I agree it's a relatively large patch for a release candidate but if >> prudence suggests deferring it, it should be a *definite* for 2.5.1 and >> subsequent releases. > > I'm not so sure it should.

As far as I am aware, it is only Windows where it doesn't work.
