It commonly represents the close front unrounded vowel {{IPA|/i/}} except in Kazakh in which it additionally represents the voiced palatal approximant {{IPA|/j/}} and the diphthongs {{IPA|/ɪj/}} and {{IPA|/əj/}}. All languages that use it also use its dotless counterpart I, but not the basic Latin letter I.

==In computing== {{Main|Dotted and dotless I in computing}}The dotted I is encoded into Unicode with the code point U+0130 (U+0069 for the lowercase letter) as part of the Latin Extended-A block.<ref>{{Cite web |title=Latin Extended-A |url=http://www.unicode.org/charts/PDF/U0100.pdf |archive-url=https://web.archive.org/web/20010603005154/http://www.unicode.org/charts/PDF/U0100.pdf |archive-date=2001-06-03 |access-date=2023-11-21 |website=Unicode Consortium}}</ref>{{charmap |0130|name1=LATIN CAPITAL LETTER<br />I WITH DOT ABOVE |0069|name2=LATIN SMALL LETTER I |map1=ISO 8859-9|map1char1=DD|map1char2=69 |map2=ISO 8859-3|map2char1=A9|map2char2=69 }}

=== 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.<ref>{{Cite web |last=Texin |first=Tex |title=Internationalization for Turkish: Dotted and Dotless Letter "I" |url=http://www.i18nguy.com/unicode/turkish-i18n.html |access-date=2023-11-21 |website=www.i18nguy.com}}</ref>

==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".{{cn|date=February 2025}}

== Diacritics == The letter İ can be found with an acute, grave, tilde, ogonek or stroke accent.

Examples:

* i̇́ * i̇̀ * i̇̃ * į̇́ * į̇̃ * 𝼚
