You have to list either the chars you want, as you have done, or the ones you don't want. You could use r'[\x00-\x1f\x7f-\xff]' or r'[^\x20-\x7e]' > 2. How do you handle the inclusion of the quotation mark " ? Use \", that works even in a raw string. By the way string.translate() is likely to be faster for this purpose than re.sub().
