sure, it's no big deal to support it, but as said .. i don't have such 
fonts (and i don't want illegal copies on my machine) so i haven't 
looked into it; also, for the few cases that are there, typescripts can 
cover it (if it concerns different font files) .. if it crosses out 
paths wolfgang and i can add it to the mkiv heuristics handler
