Unicode error
If you add non-ascii character (e.g.: ü,ä,ö,ß, é, ç, ï, etc.) in your fom layout, you get an UnicodeDecodeError Exception.
Python default encoding is ascii, and if you need language-specific characters, you have to change it to utf-8 (or other, depending on the locale language)
To do that, add a file named sitecustomize.py in Python-2.4.4/lib/python2.4/site-packages, containing the following code:
import sys
sys.setdefaultencoding('utf-8')
And then restart Zope.
