Appearance of S-cedilla in upper- and lower-case. The left is in the upper-case.
S-cedilla (majuscule: Ş, minuscule: ş) is a letter used in some of the Turkic languages. It occurs in the Azerbaijani, Gagauz, Turkish, and Turkmen alphabets. It is also planned to be in the Latin-based Kazakh alphabet.
It is used in Brahui,[1]Chechen, Crimean Tatar, Kurdish, and Tatar as well, when they are written in the Latin alphabet.
In early versions of Unicode, the Romanian letter Ș (S-comma) was considered a glyph variant of Ş, and therefore was not present in the Unicode Standard. It is also not present in the Windows 1250 (Central Europe) code page. The letter was only added to the standard in Unicode 3.0, and some texts in Romanian still use Ş instead.
