Dotted and dotless I
Some of the other Turkic languages that use the Latin script, like Azerbaijani and Tatar, also use both kinds of I. But in all these languages, including Turkish, the letter j does not have a dotted or dotless form, with a dot only on the lower case character (J, j), just like in the Indo-European languages. However, a dotless j, ȷ, does exist in Unicode.
