U+237B "⍻" Not Check Mark Unicode Character
Unicode Version 17.0
⍻
U+237B "⍻" Not Check Mark is a distinctive symbol from the APL (A Programming Language) character set, specifically designed to represent a negative or contradictory response to a check mark's affirmative meaning. Its appearance resembles a check mark with a diagonal line or slash through it, visually indicating rejection, cancellation, or failure of a test or condition. This glyph is primarily used in technical and mathematical contexts, such as APL programming or formal logic notation, where it serves as a unary operator or a marker for logical negation in contrast to a standard check mark’s acceptance.
