U+3191 "㆑" Ideographic Annotation Reverse Mark Unicode Character

Unicode Version 17.0

U+3191 "㆑" Ideographic Annotation Reverse Mark is a small, specialized symbol used within the CJK (Chinese, Japanese, and Korean) script system, primarily serving as a typographic annotation marker to indicate the reverse or opposite reading order of a text segment, often found in older or scholarly texts where it functions similarly to a reversed or flipped version of the standard annotation mark. It belongs to the Kanbun block, which includes marks used to annotate Classical Chinese texts for Japanese readers, helping to clarify grammatical structure or word order without altering the original characters. Its specific shape, a simple vertical or angled line with a slight hook, distinguishes it from other annotation marks, ensuring precise guidance for correct interpretive parsing in complex linguistic contexts.
