Yes, unfortunately.

I can see it, but I've 2.12.XX and this should be fixed. This is the 
code in http.py:

     def getPreferredCharsets(self):
         '''See interface IUserPreferredCharsets'''
         charsets = []
         sawstar = sawiso88591 = 0
         header_present = bool(self.request.get('HTTP_ACCEPT_CHARSET'))
         for charset in self.request.get('HTTP_ACCEPT_CHARSET', 
'').split(','):
             charset = charset.strip().lower()

isn't HTTP_ stripped from the request variable name?

can you send me your workaround? Maybe it can help :P
