U+2968 "⥨" Rightwards Harpoon with Barb Up Above Leftwards Harpoon with Barb Up Unicode Character

U+2968 "⥨" Rightwards Harpoon with Barb Up Above Leftwards Harpoon with Barb Up is a mathematical symbol found in the Supplemental Arrows-B block, designed to represent a bidirectional harpoon configuration where two harpoons, one pointing right and one pointing left, are vertically stacked, both with their barbs oriented upward. This character is typically used in mathematical notation, particularly in fields like category theory or topology, to denote a specific type of relation, map, or operation that involves two-way, asymmetrical interactions with a directional "above" relationship. It should not be confused with a simple double-headed arrow, as the upward barbs indicate a precise, non-reversible structural property, often describing adjoint functors or other paired but distinct morphisms.
