İ, ori, calleddotted I ori-dot, is a letter used in theLatin-script alphabets ofAzerbaijani,Crimean Tatar,Gagauz,Kazakh,Tatar, andTurkish. It commonly represents theclose front unrounded vowel/i/ except in Kazakh in which it additionally represents thevoiced palatal approximant/j/ and the diphthongs/ɪj/ and/əj/. All languages that use it also use itsdotless counterpart I, but not the basicLatin letter I.
The dotted I is encoded into Unicode with the code point U+0130 (U+0069 for the lowercase letter) as part of theLatin Extended-A block.[1]

The dotted and dotless I characters have caused issues in computing. Languages like Turkish have four variants of the letter I (opposed to two in English). This causes problems when, instead of the original mapping ofi toI, Turkish mapsi to the newİ, andı toI, frequently breaking software logic.[2]
Both the dotted and dotless I can be used in transcriptions ofRusyn to allow distinguishing between the lettersЫ andИ, which would otherwise be both transcribed as "y", despite representing different phonemes. Under such transcription the dotted İ would represent the CyrillicІ, and the dotless I would represent either Ы or И, with the other being represented by "Y".[citation needed]
