x21B8

x21B8, often written as U+21B8, is the hexadecimal designation for a Unicode code point in the Arrows block. This range is dedicated to arrow-like symbols used in mathematics, diagrams, and user interfaces. The glyph associated with U+21B8 is font-dependent; in many fonts it renders as a leftward-pointing arrow or a closely related variant.

Encoding and representation: In UTF-8, U+21B8 is encoded as E2 86 B8. In UTF-16, it is represented as 0x21B8, and in UTF-32 as 0x000021B8. As a character in the Basic Multilingual Plane, it is supported by most modern fonts and rendering systems, though appearance can vary between typefaces.

Usage: x21B8 is primarily used to indicate direction, flow, or mapping in diagrams, charts, technical documentation, and mathematical notation. Because it is a general-purpose arrow symbol, it does not carry additional semantic meaning beyond the direction it conveys. When included in prose or UI design, authors often provide a textual description to clarify its intent, improving accessibility for screen readers and alternative renderings.

See also: Other arrow characters in the same block, such as adjacent code points in the U+21B0 to U+21BB range, which cover a variety of arrow shapes and styles. For practical use, ensure font support and consider providing descriptive text where arrows convey specific information to maintain accessibility and legibility.
