I'm fairly sure that b'M\x81\x81\xfcnster' is 'Münster'. It decodes to
that in Latin-1 if you remove the \x81 bytes. The question then is
what those extra bytes are doing there. I suspect that they and 0x9d
are just non-printing junk control bytes from the C1 set that got
inserted into the character stream somehow.
