Unicode Version 17.0
⇵
U+21F5 "⇵" Downwards Arrow Leftwards of Upwards Arrow is a specialized typographic symbol that represents two opposing vertical arrows placed side by side, where a downward pointing arrow appears to the left of an upward pointing arrow. This character is often used in technical and mathematical contexts to indicate bidirectional vertical movement, such as in diagrams showing flow processes, sorting algorithms, or user interface controls for collapsing or expanding content. Its design conveys a simultaneous upward and downward direction, with the leftwards placement of the downward arrow adding a subtle spatial cue to the directionality of the symbols.
