U+21BC "↼" Leftwards Harpoon with Barb Upwards is a typographic symbol typically used in mathematical notation, particularly in the fields of logic, set theory, and functional analysis, to represent a leftward pointing arrow with a barb that opens upward, often indicating a specific directional mapping or transformation, such as a leftward vector or a reversed implication where the upward barb distinguishes it from a standard arrow. It belongs to the Arrows block in Unicode, where it serves alongside similar harpoon symbols to denote precise relational or directional relationships in diagrams and technical writing, providing a clear visual cue for leftward movement that also incorporates a vertical orientation on one end.
