U+3199 "㆙" Ideographic Annotation First Mark Unicode Character

Unicode Version 17.0

U+3199 "㆙" Ideographic Annotation First Mark is a specialized symbol used within CJK (Chinese, Japanese, and Korean) text processing as one of a set of ideographic annotation marks, primarily to label the very first item or initial point in a list, sequence, or set of notes. It belongs to the Unicode block "Kanbun," which originates from traditional Japanese annotation systems for classical Chinese texts, where such marks were employed to indicate reading order and grammatical structure. In modern usage, this character serves a similar enumerative function, allowing writers to explicitly designate a primary or original reference point within scholarly, liturgical, or technical annotations without relying on punctuation or alphabetical markers.
