Dotless I

In some fonts, if the lowercase letters fi are placed adjacently, the dot-like upper end of the f would fall inconveniently close to the dot of the i, and therefore a ligature glyph is provided,[2] usually with the top of the f extended to serve as the dot of the i. A similar ligature for ffi is also possible. Since the forms without ligatures are sometimes considered unattractive and the ligatures make the i dotless, such fonts are not appropriate for use in a Turkish setting. However, the fi ligatures of some fonts do not merge the letters and instead space them next to each other, with the dot on the i remaining. Such fonts are appropriate for Turkish, but the writer must be careful to be consistent in the use of ligatures.

The dotless ı may also be used as a stylistic variant of the dotted i, without there being any meaningful difference between them.

This is common in older Irish orthography, for example, but is simply the omission of the tittle rather than a separate letter. The í is a separate letter as is ì in Scottish Gaelic. Though historically Irish only used an "i" without a dot, so as to not confuse with "í", this dotless "ı" should not be used for Irish. Instead a font with "i" in the normal location should be used that has no dot. See other old style Irish letters and the symbol for & still used in modern Irish text and Irish orthography.

In some of the Athabaskan languages of the Northwest Territories in Canada, specifically Slavey, Dogrib and Chipewyan, all instances of i are undotted to avoid confusion with tone-marked vowels í or ì.

Lowercase dotless ı is used as the lowercase form of the letter Í in the official Karakalpak alphabet approved in 2016.

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".

• İ, the letter's dotted counterpart
• Tittle: the dot above "i" and "j" in most of the Latin scripts
• Yery (ы), a letter used to represent [ɯ] in Turkic languages with Cyrillic script, and the similar [ɨ] in Russian
• I with bowl, a letter that represented [ɯ] in the Latin-based Yañalif alphabet used for the Turkic languages of the former Soviet Union prior to those languages' adoption of Cyrillic
