Unicode Version 17.0
↭
U+21AD "↭" Left Right Wave Arrow is a typographic symbol that depicts a bidirectional arrow with a wavy, undulating shaft, suggesting a wavering or oscillating movement from left to right and back. It is commonly used in mathematics, logic, and formal notation to represent a reversible or alternating relationship, such as a two-way dynamic process or a non-rigid equivalence. In textual contexts, it can also convey hesitation, uncertainty, or a back-and-forth motion in diagrams or abstract representations, distinguishing it from the more rigid straight bidirectional arrow.
