U+0326 "̦" Combining Comma Below Unicode Character

U+0326 "̦" Combining Comma Below is a diacritical mark used in various writing systems to modify the sound of a base letter by adding a small comma-shaped symbol underneath it. This combining character is most notably employed in Romanian orthography, where it forms the letters Ș (S-comma) and Ț (T-comma), distinguishing their pronunciations from those of the standard S and T. It also appears in certain Latin-based transcriptions and minority language scripts, functioning as a visual indicator for a specific phonetic quality, such as a hissing or affricate sound, when placed beneath its host character.
