Letters
Fragment of a discussion from User talk:Afc0703
You said it yourself: the other languages add letters. Italian adds no letters but omits J, K, W, X, and Y from its alphabet. Those letters still have names and we have entries for them, but they're not counted in the order of the alphabet.
With that, do you suggest we concentrate on the Italian order and treat the omitted letters as we would Greek or other foreign letters?
