U+21B3 "↳" Downwards Arrow with Tip Rightwards Unicode Character

U+21B3 "↳" Downwards Arrow with Tip Rightwards is a typographic symbol that combines a downward vertical line with a small rightward arrowhead at its end, visually suggesting a change in direction or a branching path. It is commonly used in mathematics, computer science, and interface design to denote operations such as a function mapping to a result, a flow or transition in a diagram, or the action of opening a menu or expanding a list. Unlike plain arrows, its unique shape conveys a specific shift from a vertical to a horizontal orientation, making it useful for representing downward movement that continues sideways or for indicating a subcategory within a structured hierarchy.
