My claim is not only not customary now, but never were.

The decimal digits are younger than the Arabic and Latin scripts.

The difference between U+0662 and U+06F2 is that the former is bidi=AN
and the latter is bidi=EN.  My question was whether that difference was
anything more than a coding convention.  If there is a difference, then
perhaps the Maghribi forerunners of European digits need to be encoded
as bidi=AN.
