I forgot to mention I was using 4Suite0.9.0. The problem may not occur
with older versions of 4DOM (I don't know which one is included in
pyxml). To know, just check if Print (in xml.dom.ext.__init__.py) takes an
'encoding' argument.

This is being sorted out on 4Suite's mailing list. Basically what I have
is something like:

from xml.dom.ext.reader import Sax2
from xml.dom.ext import Print
d= Sax2.FromXml('''<?xml version="1.0" encoding="iso-8859-1"?>
# The following works fine, because the parser converted my iso-8859-1
# characters to UTF-8
# to get a readable input, I have to use:

# Now if I create nodes manually, I have a problem:
t=d.createTextNode("le mois d'août est chaud")
# The next statement prints both text node 'as is' : the first one is
# UTF-8 and the second one is iso-8859-1
# If I ask for a print as iso-8859-1, I get an error when the second text
# node is being converted. Full traceback available on request. 

What was concluded on 4Suite ML was that I needed python 2 to get 'native'
support for unicode, and that until the I would have to convert by
hand. :o(
