If news is UTF-8, raw, there must be some mechanism to e-mail that
content to a moderator, have them be able to read it at least well
enough to decide how to moderate it, and then be able to send it
back in some format that preserves the content with their additional
approval (which most likely implies UTF-something).
it's certainly possible to do this if you can get moderators
to run new code. however expecting this functionality to already be
implemented in existing software is hopelessly unrealistic.
