Most of those characters are hard to see.
Represent arbitrary characters in a string in hex: "\x00\x01\x02" or
If you just want to remove some characters, look into "".translate().
nullxlate = "".join([chr(n) for n in xrange(256)])
delchars = nullxlate[:31] + chr(124)
outputstr = inputstr.translate(nullxlate, delchars)
