U+21C7 "⇇" Leftwards Paired Arrows Unicode Character
Unicode Version 17.0
U+21C7 "⇇" Leftwards Paired Arrows is a typographic symbol classified under the "Arrows" block, specifically representing two parallel leftward arrows that are often used to indicate a bidirectional process or a two-way communication channel, with emphasis on the leftward direction. It conveys the notion of simultaneous movement or exchange in a leftward orientation, making it useful in fields like physics for representing conjugate pairs, in logic for double implications, or in diagrams showing synchronous processes. The character is visually distinct from a standard arrow by its dual design, and it can be found in mathematical notation, technical documentation, and user interface icons where a clear, non-standard directional signal is needed. As an entity encoded in the Universal Coded Character Set, it ensures consistent representation across different platforms and software for specialized symbolic communication.
