Unicode Version 17.0
⤜
U+291C "⤜" Rightwards Double Arrow-Tail is a typographic and mathematical symbol that depicts a double-lined arrow pointing to the right, distinguished by a small "tail" or barb at its base on the left side, which gives it a hooked appearance. This glyph is typically used in technical notation, particularly in logic, set theory, or computer science, to represent a specialized directional relationship, such as a mapping, implication, or functional transformation that incorporates a specific binding or constraint indicated by the tail. It belongs to the Supplemental Arrows-B block of Unicode, designed for advanced technical and academic contexts where precision in arrow notation is required.
