[Zope] Having problems with the umlauts in Zope 2.6.0

Hi, in Zope 2.5.1 everything worked perfect. I stored texts in the string properties of my ZClasses with the special german characters (ä,ö,ü) and there weren't problems. Today I realized that when I tried to do it with my new Zope (2.6.0), it refuses to accept them. I look in the list and found that I could use: import sys sys.setdefaultencoding("latin-1") I put it in my z2.py script, but it says that sys doesn't havean attribute 'setdefaultencoding'. Even from the command line I get the same error. How can I solve this problem? Thanks in advanced, Josef
