In theory the log file could be encoded in some way, and could include 
spaces in usernames.  Maybe in this case unicode should be allowed, and 
spaces allowed, with the caveat that the log file may not represent 
this?  So for a common log:

   if isinstance(username, unicode):
       username = username.encode('ascii', replace)
   username = username.replace(' ', '')

It is up to the consumer to handle any unicode, and to maintain the 
integrity of their log format regardless of input.
