U+2263 "≣" Strictly Equivalent To Unicode Character

U+2263 "≣" Strictly Equivalent To is a mathematical symbol that denotes a stronger form of equivalence than a simple equals sign, often used in formal logic, abstract algebra, and advanced mathematics to indicate that two expressions or objects are identical in all relevant contexts, including structure and meaning, not just in value or outcome. It is distinct from symbols like "≡" (identical to) or "=" (equals) because it emphasizes an absolute, definitional equivalence, such as in set theory or equivalence relations where no transformation or interpretation can alter the identity. This symbol is included in the Unicode block for Mathematical Operators, allowing it to be consistently represented across digital platforms for precise technical communication.
