U+3192 "㆒" Ideographic Annotation One Mark Unicode Character

Unicode Version 17.0

U+3192 "㆒" Ideographic Annotation One Mark is a small, enclosed numeral originally used within East Asian, particularly Japanese, printed texts to serve as a superscript-like annotation marker, typically placed beside or above a character to indicate the first item in a sequence or the primary meaning in a set of glosses. It is part of the CJK Compatibility block and is often paired with similar marks for two, three, and four to create a simple numbered reference system for annotating classical texts or modern educational materials. While its usage has largely been superseded by standard Arabic numerals or other modern annotation methods, it remains encoded in Unicode for compatibility with older documents and specialized typographic traditions.
