All,
I now have the CSX+ fonts I sought, in both Open type and Adobe formats. These are readily available as I have since discovered.
However, I still seek Charles Wikner's font - a different font, which I should have made clear.
It is a postscript font, (Unix) which he had developed himself in the early days, to produce his Sanskrit Introductory.
A postscript to open type (Windows) font conversion would therefore have been needed.
In the meantime, I'll try and locate a good conversion tool, myself.
Thanks again,
