U+319B "㆛" Ideographic Annotation Third Mark Unicode Character

U+319B "㆛" Ideographic Annotation Third Mark is a small, stylized symbol used within traditional Chinese and Japanese textual annotation, specifically as part of a system of punctuation marks known as "ideographic annotation marks." It denotes the third level of commentary or the third item in a sequence of notes, often appearing beside classical text to indicate a sub-commentary or a third-order explanation, distinct from the first and second marks. This mark is part of a set that helps organizers and readers navigate layered annotations in scholarly editions, particularly in East Asian manuscript and print traditions. It is encoded in the Unicode standard under the CJK Compatibility Ideographs block, serving as a standardized representation for this precise semantic and typographic function.
