U+21C1 "⇁" Rightwards Harpoon with Barb Downwards Unicode Character
Unicode Version 17.0
⇁
U+21C1 "⇁" Rightwards Harpoon with Barb Downwards is a typographic symbol often used in mathematical notation, logic, and diagrams to represent a rightward direction of flow or connection that implies a downward component, such as in chemical equations, function mappings, or adjacency lists. It appears as an arrow with a small barb or triangular head at its tip, with the barb opening downward rather than pointing straight along the shaft, distinguishing it from a simple right-pointing arrow. This harpoon is part of the Arrows block and can be employed in technical documentation, textual interfaces, or informal notation to indicate a temporary or specific directional link that is not strictly horizontal.
