U+302C "〬" Ideographic Departing Tone Mark Unicode Character

U+302C "〬" Ideographic Departing Tone Mark is a small, diagonal stroke used in East Asian typography, specifically as a diacritical mark within the Chinese rime dictionary tradition to denote the departing tone (qùshēng) of a character in Middle Chinese phonology. It appears as a narrow, angled line placed above or beside an ideograph, functioning as a phonetic notation rather than a standalone punctuation mark, and is part of the CJK Symbols and Punctuation block, where it aids in historical linguistic studies and the accurate annotation of classical texts.
