U+21D8 "⇘" South East Double Arrow Unicode Character

U+21D8 "⇘" South East Double Arrow is a typographical symbol classified under the Arrows block in the Unicode standard, representing a double-lined arrowhead that points diagonally downward and to the right. It is primarily used in mathematical notation, technical diagrams, and user interface design to indicate movement, direction, or a mapping toward the southeast quadrant. The double stroke distinguishes it from a standard single-line arrow, often implying a stronger or bidirectional conceptual relationship when paired with other arrows. While less common in everyday text, it serves as a precise visual cue in contexts such as flowcharts, coordinate systems, or vector graphics where clear directional signaling is required.
