U+3197 "㆗" Ideographic Annotation Middle Mark Unicode Character

Unicode Version 17.0

U+3197 "㆗" Ideographic Annotation Middle Mark is a specific symbol used within CJK (Chinese, Japanese, and Korean) text processing, primarily to denote the middle position or central concept in an annotated sequence. It belongs to a set of ideographic annotation marks that were historically employed in Korean glosses, known as Gugyeol or To, where they were placed alongside Chinese characters to indicate grammatical relationships or reading order without altering the original text. This particular mark represents the notion of "middle" or "center," acting as a visual clue for interpreters or readers to understand the syntactic or semantic midpoint of a phrase. Though its use in modern digital contexts is rare, it remains an important piece of East Asian typographic history and is preserved in Unicode for faithful representation of classical Korean and some Japanese annotated texts.
