Sure, you are using "str.encode" in a wrong way:

  "str.encode('uft-8')" is equivalent to
  "unicode(str, getdefaultencoding()).encode('utf-8')".


What encoding should your "200" use?

   Convert it to unicode using this encoding (and let the
   ZPublisher convert the unicode to "utf-8").


By the way, your exception must come from somewhere else
as "chr(200)" cannot lead to a "byte 0x80".

It is always worth to look at the traceback. It tells you
where the exception really comes from...

You should use Unicode in XML mode...
