U+2958 "⥘" Upwards Harpoon with Barb Left to Bar Unicode Character

U+2958 "⥘" Upwards Harpoon with Barb Left to Bar is a typographic symbol from the Supplemental Arrows B block, used in mathematical and technical notation to represent a specific directional relationship or mapping. It depicts a vertical arrow pointing upward, with a barb on the left side of its head, where the shaft of the arrow also connects to a horizontal bar near its base, often employed in diagrams for set theory, category theory, or logic to indicate a constrained upward movement or function that originates from a boundary or fixed point. This character is distinct from simpler arrow symbols due to its combination of a barb and a bar, which conveys additional structural information in formal systems.
