U+2959 "⥙" Downwards Harpoon with Barb Left to Bar Unicode Character
Unicode Version 17.0
⥙
U+2959 "⥙" Downwards Harpoon with Barb Left to Bar is a typographic symbol used in mathematical notation, particularly in the field of category theory and homological algebra, to represent a specific type of arrow or mapping. Its design features a downward-pointing harpoon with a small barb on its left side, which is drawn so that the shaft ends at a vertical bar, indicating a relation or attachment to that bar. This character is part of the Supplemental Arrows-B block in Unicode, and it helps convey nuanced directional relationships in diagrams and proofs where standard arrows are insufficient.
