U+1135D "𑍝" Grantha Sign Pluta Unicode Character

U+1135D "𑍝" Grantha Sign Pluta is a diacritical mark used in the Grantha script, which is historically employed for writing Sanskrit and classical Manipravalam in South India. This sign specifically indicates a pluta or prolonged vowel, where the vowel sound is held for an extended duration, typically three morae in length, as per ancient grammatical rules. Placed above or attached to a base character, it modifies the pronunciation of the vowel in religious, scholarly, or prosodic texts, distinguishing it from standard short or long vowels. The Grantha script itself is a Brahmic abugida that predates modern South Indian scripts like Tamil and Malayalam, and this character preserves a key phonetic nuance from Sanskritic tradition.
