U+21A2 "↢" Leftwards Arrow with Tail Unicode Character

U+21A2 "↢" Leftwards Arrow with Tail is a typographic symbol that belongs to the Arrows block, specifically designed to represent a leftward pointing arrow with a short, perpendicular line or "tail" attached to the back of its shaft. Unlike the standard leftwards arrow, this tail adds a distinct visual cue often used in mathematics, logic, or technical diagrams to denote a specific type of mapping, implication, or directional control, such as indicating a leftwards association with a constraint or a modified direction in formal notation. Its design ensures clarity in contexts where simple arrows might be ambiguous, making it a helpful tool for precise symbolic communication.
