Yes, but if you're using vfs created by fontinst (which you don't since you
don't use vfs), it handles missing glyphs differently.  There is (AFAIK) no
way for a TeX to tell the difference between a missing glyph rule in a vf
and a real glyph.

The advantage of this method is that you get to see exactly where the
problem is without having to muck around with log files and whatnot:
there's a big black splodge on the page which you can't miss.  The problem
with it is that TeX can't know about the problem.  I don't believe that
your TeX can know about it either.
