U+319E "㆞" Ideographic Annotation Earth Mark Unicode Character

Unicode Version 17.0

U+319E "㆞" Ideographic Annotation Earth Mark is a small, stylized square used in traditional East Asian textual annotation, primarily associated with the "Earth" element in the "Heaven, Earth, Man" triad from the Yijing (I Ching). This mark was historically employed in Classical Chinese and Japanese kanbun texts to indicate a reference or annotation related to the Earth phase, often placed beside or above characters to guide the reader's interpretation or to denote a secondary layer of commentary. It belongs to the Kangxi Radicals block in Unicode, which encodes these legacy marks used by editors and scholars to disambiguate or clarify meaning in densely annotated manuscripts. The glyph itself is derived from the ideograph for "earth" (地), simplified and miniaturized for annotation purposes.
