U+2216 "∖" Set Minus Unicode Character
Unicode Version 17.0
∖
U+2216 "∖" Set Minus is a mathematical symbol that represents the set difference operation in set theory, denoting the removal of elements belonging to one set from another. It is visually distinct from the standard backslash character, as it is designed to align properly with mathematical notation and avoid confusion with programming or typographic uses. This symbol is commonly employed in academic contexts, such as when expressing that set A minus set B yields the elements present in A but not in B. Its inclusion in Unicode ensures consistent representation across digital platforms for mathematical text.
