If the Swedish registry allows all the letters used in Swedish and Sami, and far eastern registries allow Chinese characters, the Turkish and Azerbaijani registries should allow, and be allowed to allow, all the letters of the alphabets of their national languages.
They would in that case allow dotted and dotless i, but would they automatically allow dot above? There's still the uppercase/lowercase problem, though---maybe these registries should not allow different domain names that differ only in dotless/dotted "i"?
