Rightwards Open-Headed Arrow

Rightwards Open-Headed Arrow at U+21FE is a right-pointing arrow with an unfilled, V-shaped head, used to mark direction, mapping, or movement to the right. It sits in the Arrows block, among specialized arrow symbols for mathematical notation, diagrams, and technical text. In practice, this character is most at home in formal or semi-formal notation where an arrow should look lighter than a filled or solid-headed arrow. Mathematicians and textbook authors may use it for functions, transformations, or directed relationships when they want to distinguish it from the more common right arrow, as in a custom notation where A ⇾ B means a particular kind of transition. It also appears in schematic diagrams, flow descriptions, and plain-text technical notes as a compact “leads to” or “moves toward” marker. Because the open head is a stylistic distinction rather than a universally fixed meaning, its exact interpretation usually depends on the surrounding legend, discipline, or author’s convention.
