Using 8N1 when it's really 7M1 means you have the high bit set on
every byte. I don't know if there's an easy way to do this fast in
Python, but what you need to do is mask them all off... I'm not sure
if there's a better way, but this ought to work:

string = "".join(chr(ord(x)&0x7f) for x in string)

In Python 3, iterating over a 'bytes' string produces integers, so
omit the ord() call. Other than that, code is not tested.
