yes this seems the root of the problem. The pfb files were converted using
a number of tools and I honestly cannot recall exactly how it was done.
there is a tugboat article
about it.

from vnr fonts will have this problem, and it will take quite a lot of
time/work to fix.
I wish I had the time to fix this problem, but I have other things that
have higher priority
on my todo list.

If someone would like to work on this, I will do my best to make all info
and tools available.
