U+21AC "↬" Rightwards Arrow with Loop Unicode Character

U+21AC "↬" Rightwards Arrow with Loop is a typographic symbol that depicts an arrow pointing to the right with a small, circular loop attached to its tail, visually suggesting a path that turns back on itself or indicates a cyclic process. It is part of the Arrows block in Unicode and is commonly used in mathematical notation, logic, or diagrammatic contexts to denote concepts such as a recursion, a feedback loop, or a mapping that returns to a prior state. This character can also appear in phonetic alphabets or informal writing to represent a curving or redirected action, and it is often encoded in web pages and digital documents for precise symbolic communication.
