| This wouldn't be needed today, since python is now Unicode friendly. You have
| Unicode strings being passed to your SAX methods, and on the output side, the
| EUC-JP or ISO-2022-JP codec used by the XML serializer will convert to bytes
| all the characters supported by those encodings. The non-ASCII range of
| ISO-8859-1 (\u00A0-\u00FF) would not be handled by the codecs, but the XML
| serializer will simply deal with that by emitting numeric character references
| automatically.

Thank you for the tip, but I was not able to figure out how to
realize what you suggested.  To the best of my knowledge, the
method ContentHandler.characters() determines how characters are
to be handled on the output side.  So, encoding-related things
won't be _automatically_ done.  I've missed something important?

Thanks,
