I can't reproduce this on Python 2.3.6 or 2.4.4 on RHEL 4. Instead, I
get the usual...
('CHARACTERS', <DOM Text node "Simon\u2019s XM...">)
And I can get the content of the text node as a proper Unicode object.

Yes, it is possible, at least in Python 2.3.6 and 2.4.4 configured
with --enable-unicode=ucs4 (which is what Red Hat does and expects).
P.S. You shouldn't try and pass Unicode to the parser, since XML
parsing in its entirety deals with byte sequences and character
encodings, although I suppose that there's some kind of character-
based (ie. Unicode value-based) parsing method defined somewhere by
some committee or other.
