T-comma

T-comma (majuscule: Ț, minuscule: ț) is a letter which is part of the Romanian alphabet, used to represent the Romanian language sound /t͡s/, the voiceless alveolar affricate (like ts in bolts). It is written as the letter T with a small comma below and it has both the lower-case (U+021B) and the upper-case variants (U+021A). It is also a part of the Gagauz alphabet and the Livonian alphabet.

The letter was proposed in the Buda Lexicon, a book published in 1825, which included two texts by Petru Maior, Orthographia romana sive Latino-valachica una cum clavi and Dialogu pentru inceputul linbei române, introducing ș for /ʃ/ and ț for /t͡s/.^[1]

This letter was not part of the early Unicode versions, which is why Ţ (T-cedilla, available from version 1.1.0, June 1993) is often used in digital texts in Romanian. T-comma was introduced only in Unicode 3.0.0 (September 1999) at the request of the Romanian national standardization body, but many computers today still do not have fonts compatible with it; computers with Microsoft operating systems older than Windows XP do not have compatible fonts. Windows XP's default fonts do not support this letter out of the box, but it is possible to install the European Union Expansion Font Update,^[2] which adds support for this letter. That is why almost all Romanian texts still use T-cedilla (or even T), despite the recommendation to migrate from cedilla to comma. Full support of this letter has been available on Macintosh computer since Mac OS X and is now provided by Windows Vista.

In Windows XP, most of the fonts including the Arial Unicode MS render T-cedilla as T-comma because T-cedilla is not used in any language. Technically, this is incorrect as a mismatching glyph is associated with a certain character code. Therefore, text written using S-cedilla and T-cedilla can often be seen as if it had been written using S-cedilla and T-comma. However, in order to correctly encode and render both S-comma and T-comma, one has to install the European Union Expansion Font Update. Unfortunately, there is no official way to add keyboard support for these characters. In order to type them, one has to either install 3rd party keyboards, or use the Character Map.

The Windows version of the Firefox web browser is able to generate S-comma and T-comma, even if the characters are missing from the system's fonts. Internet Explorer does not have this capability.

All Linux distributions are able to correctly render S-comma and T-comma, since at least 2005. If these characters are missing from a certain font, they will be substituted with the glyph from another font. Although the X.Org Server supports the correct keyboard (ro comma) since at least 2005, selecting this keyboard from the user interface (e.g. GNOME Keyboard Properties) has only recently been made possible.
