Many thanks for the information, Reinhard : very helpful.

I thought (but it is a long time since I played with
such things) that all I would need to do was to create
a VP file (virtual property list) specifying one
or more base fonts and the necessary mappings, and
then convert this to a VF.  Have I misunderstood
(or mis-remembered) this ?
