U+21EC "⇬" Upwards White Arrow on Pedestal with Horizontal Bar Unicode Character

U+21EC "⇬" Upwards White Arrow on Pedestal with Horizontal Bar is a typographic symbol found in the Arrows block, designed as a hollow or outlined arrow pointing upward, set atop a pedestal that includes a horizontal bar across its base. This glyph is primarily used in technical notation, mathematics, or diagrammatic contexts to represent concepts such as an upward shift, a logical or electrical reset, or a specific directional movement constrained by a base level. Its appearance combines an upward directional cue with a stable support structure, distinguishing it from simpler arrow symbols and suggesting a relationship between vertical motion and a fixed reference point.
