Is this faster? It replaces all occurrences of each control character
in ctrlcmap for the whole string you pass to it.

ctrlcmap = dict((chr(x), repr(chr(x))[1:-1]) for x in range(160) if x
< 32 or x > 126 and x < 160)
teststring = chr(127) + 'mytestring'

def _cleanRepr(text, ctrlcmap):
    for ctrlc in ctrlcmap.keys():
         text = text.replace(ctrlc, ctrlcmap[ctrlc])
    return text

>>> teststring
'\x7fmytestring'

>>> _cleanRepr(teststring, ctrlcmap)
'\\x7fmytestring'
