Thanks a lot Jonathan! This is exactly what I wanted to know, but was
afraid to ask...
I am writing a few macros for Plain XeTeX in order o use your
suggestion in other situations (footnotes, section numbers and so on)
for Persian (and Arabic). When they are clean I'll let know the
community.
I imagine that there is more or less the same procedure in order to
have Persian or Arabic numbers in math mode (the above command does
not produce what is wanted).
Again thank you very much!
Best regards: OK
