Upwards White Double Arrow

Upwards White Double Arrow at U+21EE is a hollow double-stem arrow pointing upward, used as a symbolic arrow rather than a letter or punctuation mark. It is part of the Arrows block, alongside many directional and operator-style arrow signs for diagrams, notation, and interface symbols. Its most recognizable use is in keyboard and user-interface notation, where it can stand for a strong upward action such as a shift, raise, upload, or move-to-top command when a designer wants a more emphatic symbol than a single up arrow. In technical diagrams or flowcharts, ⇮ may mark an upward transition, promotion, or transfer between levels. It also appears in mathematical or logical writing when authors need a visually distinct upward arrow relation, although it is far less common than standard up arrows or implication arrows. Because it is a white, outlined form, it is often chosen in symbol charts, documentation, and decorative UI text for contrast with filled double-arrow variants.
