0x21B2

0x21B2 is a hexadecimal notation used in computing to refer to the Unicode code point U+21B2. In the Unicode standard, code points uniquely identify characters, and U+21B2 resides in the Arrows block, a range of symbols commonly used to depict directional relationships in text, mathematics, and diagrams. The exact visual appearance of the character depends on the font and rendering system in use; fonts may render it as a directional arrow with various stylistic details.

Encoding and representation are central to understanding 0x21B2. In UTF-8, the character U+21B2 is encoded as the byte sequence E2 86 B2. In UTF-16, it is represented by a single 16-bit unit, 0x21B2. In many programming languages and data formats, it can be written using escape sequences such as U+21B2 or \u21B2, depending on the context.

Applications of U+21B2 include mathematical notation, flow charts, diagrams, and user interface elements where a directional indicator is required. Its use is often alongside other nearby arrow code points (for example, U+21B0 through U+21B3) to convey combinations of directions or relational arrows in a compact symbol set.

Related concepts and standards include the Unicode Consortium, which maintains the character set, and common encodings such as UTF-8 and UTF-16, which determine how U+21B2 is stored and transmitted in digital systems. The symbol’s appearance, semantics, and accessibility can vary based on font support, rendering engines, and assistive technology.
