Unicode Version 17.0
⥦
U+2966 "⥦" Leftwards Harpoon with Barb Up Above Rightwards Harpoon with Barb Up is a mathematical symbol belonging to the Supplemental Arrows-B block, used in notation for commutative diagrams and category theory to represent a bidirectional relationship or a 2-cell morphism where two parallel arrows, one pointing left and one right, each have their barbs directed upward, indicating that the two harpoons operate in opposite horizontal directions while sharing a common vertical orientation. It visually combines a leftwards harpoon above a rightwards harpoon, and its specific structure helps denote a special kind of equivalence or interaction between objects in advanced mathematical contexts, distinct from simpler bidirectional arrows.
