U+21EF "⇯" Upwards White Double Arrow on Pedestal Unicode Character
Unicode Version 17.0
⇯
U+21EF "⇯" Upwards White Double Arrow on Pedestal is a typographic symbol belonging to the Arrows block, representing two white arrows pointing upward, stacked vertically and mounted on a small base or pedestal. This character is primarily used in technical notation, mathematics, or diagrams to indicate upward movement, escalation, or a two-step increase, often implying a process that rises in stages rather than a single leap. Its design, featuring hollow arrowheads on a stem with a supporting platform, distinguishes it from related symbols like the single or double upward arrows without a base.
