U+2201 "∁" Complement Unicode Character
Unicode Version 17.0
∁
U+2201 "∁" Complement is a mathematical symbol representing the complement of a set, often used in set theory and logic to denote all elements not contained within a given set. It is a less common variant of the more widely used complement symbol (like the superscript C or the minus symbol) and is encoded in the Unicode block for mathematical operators. This character allows for precise textual representation in digital documents and programming contexts where set complement operations are needed, ensuring clarity in technical and academic writing.
