That is overly complicated.  I would recommend you use either raw 
strings for windows paths, or double backslashes.

The problem you are observing is that \x (unlike the simpler ones such 
as \t) takes a hex number after the \x, so the whole thing would be, for 
example, \xa9.  Because Python is looking for two hex digits after the 
back-slash, and not finding them, you get the error (long before your 
'fix-it' routine gets a chance to run).

Hope this helps.
