İ
Latin letter I with dot above
From Wikipedia, the free encyclopedia
İ, or i, called dotted I or i-dot, is a letter used in the Latin-script alphabets of Azerbaijani, Crimean Tatar, Gagauz, Kazakh, Tatar, and Turkish. It commonly represents the close front unrounded vowel /i/ except in Kazakh in which it additionally represents the voiced palatal approximant /j/ and the diphthongs /ɪj/ and /əj/. All languages that use it also use its dotless counterpart I, but not the basic Latin letter I.

Issues
The dotted and dotless I characters have caused issues in computing. Languages like Turkish have four variants of the letter I (as opposed to two in English). This causes problems when, instead of the original mapping of i to I, Turkish maps i to the new İ, and ı to I, frequently breaking software logic.[2]
Usage in other languages
Both the dotted and dotless I can be used in transcriptions of Rusyn to allow distinguishing between the letters Ы and И, which would otherwise be both transcribed as "y", despite representing different phonemes. Under such transcription the dotted İ would represent the Cyrillic І, and the dotless I would represent either Ы or И, with the other being represented by "Y".[citation needed]
Diacritics
The letter İ can be found with an acute, grave, tilde, ogonek or stroke accent.
