U+225B "≛" Star Equals Unicode Character
Unicode Version 17.0
≛
U+225B "≛" Star Equals is a mathematical symbol that visually resembles an equal sign with a star superimposed in its center, combining the concepts of equality and a star. It is classified under the Mathematical Operators block in Unicode and is used in specialized contexts such as formal logic, set theory, or notation systems where a distinguished or starred equality relation is needed to denote equivalence with an additional property, like being a "starred" or "special" equivalence rather than standard equality. The symbol is rarely seen in common writing but serves a precise role in technical documents and mathematical typesetting where clarity of unique relations is essential.
