Hi Tony,

I suspect that one of your UNI files being processed by StrGather has an invalid Unicode character in it.  Can you review the UNI files in the module that is being build when this error is generated?

I would be better if this code identified the file/line number with the issue, so that would be a good Bugzilla to enter.
