Hi Hans,

can you be please more specific? Do you use those fonts with tex, or
they are included in some pdf figure?

If you want to use them in the ``standard'' way, then the way to make it
work properly is to use fontinst. Fontinst is itself complicated and
hard to use as (plain) tex, but so far it is the most flexible way
(IMHO) to do that.
