u21B2

U+21B2, also written as u21B2 in plain text, is a Unicode code point in the Arrows block. Its formal name is DOWNWARDS ARROW WITH TIP LEFT. The character is a directional symbol used in mathematical notation, diagrams, and user interfaces to indicate downward movement with an offset tip to the left. It is one of several variants of vertical arrows designed to convey nuanced directional meaning in diagrams and flowcharts.

In terms of encoding, U+21B2 resides in the Basic Multilingual Plane. It is represented in Unicode by the code point 21B2 (8626 in decimal). In UTF-8, code points in this range are encoded with three bytes. In HTML, it can be included as a numeric character reference: ↲ or ↲. Rendering and exact appearance depend on the font and rendering engine being used, and some fonts may substitute a visually distinct arrow if the glyph is unavailable.

Usage and context-wise, U+21B2 is part of a broader set of arrow symbols (U+21B0 to U+21B3) that offer variants of upward and downward arrows with tips on either side. These characters are uncommon in everyday prose but appear in technical documentation, educational materials, and diagrammatic notation where precise directional symbolism is helpful. Font support varies, so some environments may render the symbol differently or omit it if a font lacks the glyph. For most practical purposes, U+21B2 functions as a specialized directional indicator within the Unicode Arrows collection.
