I think you may have uncovered an implementation bug rather than an
encoding issue (because I'd expect "" and b"" to be equivalent).
In ancient times, "" was a valid UNIX name for the working directory.
POSIX disallows that, and requires people to use ".".
Maybe you're seeing an artifact; did python move from UNIX to Windows or the
other way around in its porting history? I'd guess the former.
Do you get differing results from listdir(".") and listdir(b".") ?
How's python2 behave for ""? (Since there's no b"" in python2.)
Cheers,
