U+21AB "↫" Leftwards Arrow with Loop Unicode Character

U+21AB "↫" Leftwards Arrow with Loop is a typographic symbol that depicts an arrow pointing to the left with a small loop or curl at its tail end, often used to represent a reversal, a return, or a backward looping action in diagrams, computer interfaces, or mathematical notation. It belongs to the Arrows block in Unicode and serves as a visual cue for processes that cycle back on themselves or require a non standard direction of flow. While less common than its rightward counterpart, the leftwards arrow with loop can be found in technical documentation, flowcharts, and software menus to indicate a step that loops backwards or undoes a prior operation.
