See:

   $ mkdir /tmp/xyz
   $ touch /tmp/xyz/$'\x80'
   $ python3
   Python 3.3.2 (default, Dec  4 2014, 12:49:00)

   >>> import os
   >>> os.listdir('/tmp/xyz')
   ['\udc80']
   >>> open(os.listdir('/tmp/xyz')[0])
   Traceback (most recent call last):

   FileNotFoundError: [Errno 2] No such file or directory: '\udc80'

File names encoded with Latin-X are quite commonplace even in UTF-8
locales.
