I might be wrong, but I was under the impression that restricting the
character set was still a good idea because of downstream restrictions
on rendering of the docs.  For instance, pretty much every web browser
can render Latin1 characters, but I wouldn't bet on Klingon working.

Maybe we could go a little further than the standard named-entity
characters, but it'd take some research to figure out what is safe.
