U+29B8 "⦸" Circled Reverse Solidus Unicode Character
Unicode Version 17.0
⦸
U+29B8 "⦸" Circled Reverse Solidus is a specialized typographic symbol that belongs to the Miscellaneous Mathematical Symbols-B block, representing a reverse solidus, or backslash, enclosed within a circle. It is primarily used in mathematical notation and computer science contexts, such as in set theory or formal logic, to denote a specific operation or relation, often standing for an exclusion or a complement that is visually distinct from a regular backslash. Its design intentionally mirrors the more common circled solidus but with the slanted line reversed, allowing for clear differentiation in technical diagrams and equations where precise symbolic meaning is required.
