The modern Gagauz alphabet is a 31-letter Latin-based alphabet modelled on the Turkish alphabet and Azerbaijani. It is used to write the Gagauz language.
During its existence, it has functioned on different graphic bases and has been repeatedly reformed. Previously, during Soviet rule, Gagauz's official script was Cyrillic, close to the Moldovan Cyrillic alphabet.
I, or ı, called dotless i, is a letter used in the Latin-script alphabets of Azerbaijani, Crimean Tatar, Gagauz, Kazakh, Tatar and Turkish. It commonly represents the close back unrounded vowel /ɯ/, except in Kazakh where it represents the near-close front unrounded vowel /ɪ/. All of the languages it is used in also use its dotted counterpart İ while not using the basic Latin letter I.
In scholarly writing on Turkic languages, ï is sometimes used for /ɯ/.
