The I is used in two distinct versions in Turkic languages: [[dotless I|dotless (I ı)]] and [[İ|dotted (İ i)]]. They are considered different letters, and case conversion must take care to preserve the distinction. [[Irish alphabet|Irish]] traditionally does not write the dot, or [[tittle]], over the small letter ''i'', but the language makes no distinction here if a dot is displayed, so no specific encoding and special case conversion rule is needed as it is for Turkic alphabets.

====Statistics====
The chart above lists a variety of alphabets that do not officially contain all 26 letters of the ISO basic Latin alphabet. In this list, at least one language lacks one of every letter. For each of the 26 basic ISO Latin alphabet letters, the number of alphabets in the list above using it is as follows:
