@a.badger: Again, dropping invalid filenames in listdir() is a (very
recent) choice of the Python3 design. Please read this document which
explain the current situation of bytes vs unicode:
http://wiki.python.org/moin/Python3UnicodeDecodeError
See also issue3187 and read the long python-dev mailing list thread
about filenames (start few days ago).
Guido just commited my huge patch to support bytes filename in Python3
trunk. So using Python3 final, you will be abl to list all files using
os.listdir(b'.') or os.listdir(os.getcwdb()).
