Romanian used to use a glyph variant with a comma below (rather than cedilla) for the following characters: U+015E  LATIN CAPITAL LETTER S WITH CEDILLA, U+015F  LATIN SMALL LETTER S WITH CEDILLA, U+0162  LATIN CAPITAL LETTER T WITH CEDILLA, and U+0163  LATIN SMALL LETTER T WITH CEDILLA.

It is now recommended that Romanian data use U+0218  LATIN CAPITAL LETTER S WITH COMMA BELOW, U+0219  LATIN SMALL LETTER S WITH COMMA BELOW, U+021A  LATIN CAPITAL LETTER T WITH COMMA BELOW, and U+021B  LATIN SMALL LETTER T WITH COMMA BELOW which do not require glyph variants.
