Yup, the association with the chocolate manufacturer was the only reason – and now that you have showed me the light, it was surely a poor choice. I just wanted something to replace the asterisk I had been using.
The idea of designating the origin in the traditional way is perfect – I was clueless in that regard. I assume when you used “MT” in your suggestions that was a neural echo of the “HT” you initially suggested – your first link shows “MT” as the Monotype designator.
[Whoops – note added in proof: “HT” is already in use by Huerta Tipográphica http://www.huertatipografica.com/en#
I also searched for HM font foundry, HS… (for Hershey Modified, Hershey Style) and got too many hits for comfort. Even “EB” is in use as a prefix. What about “EG”? What do you think? ] 8^)
So, I take it you would like to use the files? If so, I’ll make the Cocoa => xx changes in the next day or two, and upload them here?
