I haven't read the rest of the responses yet but my first 
suggestion is to invert the process and use replace()

Instead of looping through every char in the string search 
for the illegal chars. A regex should enable you to do 
a single findall search. If you find any you can loop 
over the instances using replace() or sub() to change 
them. The translate module might even let you do all 
changes in one go.

That should be faster I think.
