I am loathe to be tedious, as Bruno Voisin and Will Robertson have  
already commented on this, and I have had an earlier email exchange  
on this same topic. Still, for the record...

There is a world of typographic options and subtlety available when  
this information is made available. It would not have to be for the  
entire font (if that makes any difference) but only for the  
characters in which I am interested. I don't much care about speed  
either -- if the function is slow, again, I need it, at most, for a  
handful of characters. This definitely has my vote.

Bruno Voisin's observation concerning VFs is an excellent one as  
well. Also has my vote.
