The comma is a diacritical mark of the Latin writing system that is placed under a letter.

Occurrence

  • In Romanian , the letters S and T appear with a comma ( Ș, ș , Ț, ț ). The sub-comma is called Virgulița, which means little comma. Ș, ș is pronounced like the German Sch and Ț, ț like ts.
  • In Latvian the letters G, K, L, N and (historically) R occur with a comma underneath ( Ģ , Ķ , Ļ , Ņ , Ŗ ). In Unicode they are referred to as G, K, L, N and R with cedilla . This is because they were included in the standard before 1992 and their names have been fixed ever since.
  • In Livic there are letters D ( ), L, N, R, T with a comma (where they are designated as D, L, N, R with cedilla ).

Representation on computer systems

Coding

Until the early 1990s, no distinction was made between the comma and the cedilla in international standards . Consequently, ISO 8859-2 and the Cork coding contain the letters S and T with cedilla. Only later did the view prevail that these are two different diacritics. Today , Unicode contains both S and T with cedilla and S and T with comma.

input

With the German standard keyboard layout T2 , the character is entered as Alt Gr+ k(rule of thumb: K for comma). This combination acts as a dead key , i.e. H. must be entered before the basic letter.
