[Zope] Searching Catalog for Unicode Values of FieldIndex

[Mohsen Moeeni]

Thanks Dieter for your attention.

I could get the desired result by adding this as the term prenormalizer::

python: not isinstance(value, unicode) and unicode(value, 'utf-8') or value

Dieter, I still get an exception while trying to see the Indexed objects in 
the catalog (manage_objectInformation). The problem is that 
``getEntryForObject`` tries to return ``str`` of a value. But ``str`` of Unicode
objects out of ASCII range, raises and excpetion. Full traceback below.

Cheers,
Mohsen,
