U0131

U+0131, known as LATIN SMALL LETTER DOTLESS I, is a Unicode character used in the Latin script. It represents a lowercase i without a dot and is primarily associated with Turkish orthography, where it appears as a distinct letter in the alphabet. In Turkish and some other Turkic languages, dotless i corresponds to a close back unrounded vowel, contrasting with the dotted i used in the same languages.

The character belongs to the Latin Extended-A block in Unicode and is encoded at code point 0x0131 (decimal 305). Its uppercase form maps to the standard capital I (U+0049) in Turkish orthography, while the corresponding dotted counterpart is İ (U+0130). This pairing reflects Turkish case behavior, where the lowercase i and the uppercase I are not direct dot-to-dot equivalents of the dotless and dotted variants.

In practical terms, LATIN SMALL LETTER DOTLESS I is commonly input via standard Turkish keyboards or through Unicode input methods. In HTML, it can be represented with the numeric character reference ı or the hexadecimal form ı. In UTF-8, U+0131 is encoded as the two-byte sequence C4 B1.

Related characters include LATIN CAPITAL LETTER I WITH DOT ABOVE (U+0130) and the ordinary LATIN SMALL LETTER I (U+0069). The dotless i is a specific feature of Turkish and some other languages that use a dotless variant to distinguish phonemic contrasts not represented by the dotted i.
