U+2A7C "⩼" Greater-than with Question Mark Above Unicode Character
Unicode Version 17.0
⩼
U+2A7C "⩼" Greater-than with Question Mark Above is a mathematical symbol used primarily in formal logic, set theory, and computer science to denote a relational comparison that is uncertain, questionable, or requires verification. It combines the standard greater-than sign with a superimposed question mark, visually indicating that the inequality it represents may be doubtful, hypothesized, or contingent on an unknown condition. While not common in everyday mathematics, this glyph appears in specialized texts and notation systems where precise expression of partial or hypothetical relationships is necessary, such as in proofs involving unconfirmed assumptions or in the analysis of comparative structures under investigation.
