U+21FD "⇽" Leftwards Open-Headed Arrow Unicode Character

U+21FD "⇽" Leftwards Open-Headed Arrow is a typographic symbol classified under the Arrows block, specifically representing an arrow pointing to the left with an open or unfilled arrowhead rather than a solid triangular tip. This design, where the head consists of two separated lines meeting at the tip, is used in mathematical notation, logic, and diagramming to indicate leftward movement, direction, or mapping in a less obtrusive or more formal aesthetic than solid arrows. Its open head often distinguishes it from standard arrows in technical documents or user interfaces, allowing for clear semantic differentiation in complex systems of notation.
