I think we can assume this only for the providers we own as we know it, 
but not for other providers. That's the whole reason Hans/Hant scripts 
were introduced.

Hmm, that sounds a bit overkill to me. Anyway, it definitely sounds like 
an enhancement that may be addressed with 8027313, but my intention is 
to fix this particular bug, which apparently is not working as expected 
as of now.
