Hello, I have an OpenSemanticSearch machine, c.utf\_8 encoding.  
When I create Hebrew thesaurus, I am getting following error:  
**’ascii’ codec can’t decode byte 0xd7 in position 160: ordinal not in range(128)**  
This seems to happen in Django since thesaurus is managed by Django.  
The problematic code is:

_class IncrementalDecoder(codecs.IncrementalDecoder):_  
_def decode(self, input, final=False):_  
_return codecs.ascii\_decode(input, self.errors)[0]_

How can I solve the problem or at least remove problematic entries?  
Thanks!

There are no `IncrementalDecoder` classes in django. It doesn’t seem likely that the problem is inside Django itself here. Please file the issue with `OpenSemanticSearch`.
