x21B2

x21B2 is a hexadecimal label commonly used to refer to a specific Unicode code point. In Unicode, the code point U+21B2 is part of the Arrows block and encodes a symbol that appears as an arrow. The exact appearance of the glyph depends on the font and rendering system, but it typically represents a downward-directed arrow with a secondary curvature or corner element used in diagrams and notation.

Encoding and representation details vary by system. The character is designated by U+21B2 in Unicode. In UTF-8 it is encoded as the three-byte sequence E2 9F B2. In UTF-16, it is represented as the single 16-bit unit 0x21B2. In HTML, it can be included as a numeric character reference “↲” or “↲.”

Context and usage. This symbol is used in technical documents, diagrams, and user interfaces to indicate downward direction, flow, or a transition that moves downward with a leftward element. It appears in mathematical notation, schematic diagrams, flowcharts, and educational materials where directional signaling is required. Because rendering is font-dependent, some fonts may show a more stylized or slightly different variant of the same code point.

See also. Other symbols in the Arrows block (for example U+21A9, U+2190) cover related directional glyphs and are commonly referenced when discussing arrow notation in Unicode.

Notes. In domains outside Unicode, “x21B2” might denote a product code, file name, or other identifier, underscoring the importance of context for interpretation.
