So, we have a unicode character. Before writing it out, we need to
encode it in some external character set. Consider the following:
>>> a = u'\xb5'
>>>
>>> print a
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb5' in
position 0: ordinal not in range(128)
>>>
>>> print a.encode('utf-8')

Suggestion -- You might try using the -s and the --super flags to
generateDS.py. That will generate a sub-class module that will
import your (main) generated file. Then in the sub-class where the
problem occurs, copy and modify the export method from the
super-class. Add something like the ".encode('utf-8')" to that
method. Now, process your XML with the sub-class module/file.
Once you get that working, let's talk about whether generateDS.py
should be modified so that it generates code that handles this
situation automatically and without modifications to a generated
file.
A bit of excuse making -- I had zero understanding of unicode when
I initially started work on generateDS.py. Now, at least, I have a
smidgen.
And, here is a Web page that I found very helpful:
http://farmdev.com/talks/unicode/
Excuse me if I'm insulting you here. I don't know where you are on
the unicode learning curve.
