[XML-SIG] UTF-8 and ISO-8859-1 problems again

That's a good guess. drv_xmllib does not implement handle_xml at all,
so it does not know what the encoding is. However, what it *should*
do, atleast in Python 2.0, is to produce Unicode objects, not UTF-8
encoded strings.

Would you like to look into correcting that?

Not that I know of, atleast not in PyXML 0.6.3.

I'm confused. Where did you get PyXML 1.2 from?
