We're seeing problems in one application here due to the catalog and interactions with Unicode. Here's what happens:

- an object is indexed with a Unicode title, so in the catalog the metadata tuple has for instance (u'cafe',) - later that title is changed to latin-1, so the new metadata tuple would be ('caf\xe9',)


The problem is that Catalog.py has in updateMetadata() the code:

            if data.get(index, 0) != newDataRecord:
                data[index] = newDataRecord

The simple comparison in the first line provokes a UnicodeDecodeError, you can reproduce by a simple:

    python -c "u'e' == '\xe9'"

This understandable, but in the case of the catalog really not helpful. I propose to change the code above to:

            try:
                changed = data.get(index, 0) != newDataRecord
            except UnicodeDecodeError:
                changed = True
           if changed:
                data[index] = newDataRecord

Objections ?
