Comment 2 for bug 832028

> * Python 2 doesn't give access to the unicode environment block on windows only the 'ANSI' compatiblity apis.

What does that mean in practice ? Is there at least a way for the user to specify unicode paths in *some* encoding (mbcs ?)

As long as we can trap invalid values, we can at least define which subset we can support (and report proper errors for the rest) no ?
