Neither really. The writers probably didn't anticipate anyone passing escape
sequences, as they are not only unnecessary but may cause unexpected errors
that are difficult to debug. Instead, you should pass:
"\x00-\x1f\x7f-\xff^&*()$|?<>!/\\."
Note the double quotes, and that you don't need to escape '.' in a character
class. The module should take care of any escaping needed to make the regex
work.
