Escapes???

In case you don't find some compiler switch that fixes it, here's a
simplistic mechanism that does the hex escaping (doesn't currently do the \n
etceteras, that's an exercise for the reader I suppose)...  Note the use of
raw strings in the test case!

import string

def dehex( rawstring ):
	set = string.split( rawstring, '\\x' )
	initial = set[0]
	for element in set[1:]:
		initial = initial + chr(string.atoi( element[:2], 16 ))
		initial = initial + element[2:]
	return initial

test = r"H\x1b\x23\x12art\x1b\x23\x01\n"

print `dehex( test )`

Enjoy,
Mike
