To rephrase Bruno's comment: Python supports UTF-8 as a source encoding.
That doesn't mean that

It would be easier to encode this in cp1252 here, as this is apparently
the encoding that you want to use in the RTF file, too. You could then
loop over the string, replacing all bytes >= 128 with \\'%.2x
As yet another alternative, you could create a Unico

That's the problem. If these are really utf-8 encoded byte strings,
then .lower likely won't work. It uses the C library's tolower API,
which works on a byte level, i.e. can't work for multi-byte encodings.
