U+2AEC "⫬" Double Stroke Not Sign Unicode Character

Unicode Version 17.0

U+2AEC "⫬" Double Stroke Not Sign is a mathematical symbol used primarily in formal logic and set theory to denote negation or the logical operation of "not," distinguished from the standard single-stroke negation symbol by its double horizontal line, which often emphasizes a stronger or distinct logical relationship, such as in Boolean algebras or lattice theory. It is encoded in the Supplemental Mathematical Operators block of Unicode, allowing for precise notation in digital text where typographic clarity is required. This character is less common in everyday writing but serves a specific role in advanced mathematics, computer science, and formal proofs, where it may represent the complement of a set or the negation of a statement in a way that avoids ambiguity with other similar symbols.
