U+1BF3 "᯳" Batak Panongonan is a vowel sign used in the Batak script, which is an abugida traditionally employed to write several Batak languages of Sumatra, Indonesia. This specific mark, called Panongonan, functions as a diacritic that modifies the inherent vowel of a consonant character, typically representing a long or altered vowel sound such as a long "a" or a glottal stop, depending on the specific Batak language variant. The character is encoded in the Unicode Standard's Batak block, which was introduced to preserve and digitally support this endangered writing system for modern computing.
