U+21ED "⇭" Upwards White Arrow on Pedestal with Vertical Bar is a typographic symbol defined in the Arrows block, representing a hollow or white arrow pointing upward from a horizontal pedestal that also features a vertical bar rising through its shaft. This glyph is primarily used in mathematical notation, diagrammatic logic, or interface design to denote concepts such as upward movement, elevation, or a specific directional constraint combined with a stopping or barrier indicator. Its design combines an arrow with a pedestal, suggesting a stable base, and the vertical bar implies a fixed axis or a limitation on lateral movement. While not commonly found in everyday text, it serves specialized functions in technical fields like computer science or formal logic where precise directional symbolism is required.
