So, to put it shortly, today's Persian alphabet is Arabic with several additional signs and new features, and Urdu is the same Persian script with again three extra symbols. Both Urdu and Persian are written from the right to the left.
It is almost the exact same characters as Farsi, with just 3 extra symbols apperantly. Urdu already has been implemented into the internet (unicode and all that) so i'd say it should't be that hard for FANDOM to carry? They both are similar to Arabic script, so i'll give contacting staff a try.
