U+21A5 "↥" Upwards Arrow from Bar Unicode Character

U+21A5 "↥" Upwards Arrow from Bar is a typographic symbol that depicts an upward pointing arrow whose shaft originates from a horizontal base line or bar, suggesting a concept of rising from a solid foundation or a point of origin. It is part of the Arrows block in Unicode and is often used in mathematical notation, technical diagrams, or computer interfaces to indicate an upward movement or transition that starts from a specific level or constraint. Unlike a simple arrow, the bar adds a visual anchor, making it useful for representing functions like an injection in set theory or a constrained rise in flowcharts and user interface elements.
