I’m not sure how we resolve the issue, but:

  1. ١٢٣ [661 662 663] and ۱۲۳ [6F1 6F2 6F3] look the same (123 vs 123).
  2. ١٢٤ [661 662 664] and ۱۲۴ [6F1 6F2 6F4] look different (124 vs 124).
  3. ۱۲٤ [661 662 664] and ۱۲٤ [6F1 6F2 664] look the same (124 vs 124).

If the name is pure digits, then it needs one digit from 4-6 (case 2) + the non-extended/extended exclusion rule (where second example of case 3 fails) to be valid.

If we want to support pure digit names with strictly 0-3,7-9 digits (case 1), we have to pick one. Otherwise, how do you justify case 1 and case 3 being two separate names?
