Many thanks for taking an interest in this. The font in question is a Sanskrit Diacritical Font which I obtained (free) from Padma Karpo Translation Committee http://www.pktc.org/pktc/SFTsktdiacriticals.htm to use on our yoga teachers’ website. Specifically, we are trying to use the Helvitica plain upright font hcpr_TCC.ttf which I could e-mail you. A sample of its use: śaðkha cakrāsi dhariṇam doesn’t quite come out right in this box, but you can see the characters clearly on the PKTC website.
Best regards, Michael
