   Persian / Arabic : Diodrum Arabic (6 weights)
   Latin / English  : Arian (5 weights, restricted to the Latin range)
   Arian is listed FIRST in font stacks but its unicode-range covers only
   Latin letters, digits and punctuation, so English/numbers render in Arian
   while ALL Persian/Arabic glyphs (incl. Persian digits) fall to Diodrum.
