While I think we need allow this, the subjective nature of the decision 
means that idnits can't be authoritative about it. It will probably need 
to flag most instances of UTF-8 as warnings, and in some documents there 
could be *many* of those. The only clean solution I see to that is to 
permit UTF-8 everywhere.
