U+319C "㆜" Ideographic Annotation Fourth Mark Unicode Character
Unicode Version 17.0
㆜
U+319C "㆜" Ideographic Annotation Fourth Mark is a small, specialized symbol used within CJK (Chinese, Japanese, and Korean) textual annotation systems, particularly in older or scholarly contexts, to mark the fourth item in a numbered series or to serve as a repeating placeholder within a list. Its form resembles an enclosed or stylized version of the numeral or ideographic element for "four," and it belongs to the Kanbun block, which includes marks historically employed to aid in the reading and ordering of classical Chinese texts in Japan. While not common in modern everyday writing, this character persists in certain academic, lexicographic, or formal indexing applications where a distinct and compact annotation marker is needed.
