U+225F "≟" Questioned Equal To Unicode Character
Unicode Version 17.0
≟
U+225F "≟" Questioned Equal To is a typographic symbol that combines the equality sign with a question mark, used primarily to denote a relationship that is suspected or questioned to be equal, but not yet confirmed or proven. It often appears in mathematical proofs, logical expressions, or annotations where a potential equality is under investigation, serving as a visual cue that the statement "equals" is tentative or uncertain. Unlike the more common "equals with question mark" (⁇) used in some contexts, this single glyph integrates both meanings into one distinct character for clarity in formal notation.
