U+21C8 "⇈" Upwards Paired Arrows Unicode Character
Unicode Version 17.0
⇈
U+21C8 "⇈" Upwards Paired Arrows is a typographic symbol classified under the Arrows block, depicting two vertical arrows rising in parallel, both pointing upward. It is often used in mathematical notation, technical diagrams, or logical expressions to represent paired directional movement, simultaneous ascent, or a dual increase, and it can also appear in older computing contexts as a control character or delimiter. Its design, distinct from a single arrow, emphasizes a coordinated or duplicative upward action, making it useful for illustrating concepts like joint growth or parallel processes.
