0x21A0

0x21A0 refers to the hexadecimal encoding of the Unicode code point U+21A0. In Unicode, U+21A0 is the Rightwards Two-Headed Arrow, a symbol in the Arrows block within the Miscellaneous Symbols and Arrows range. The glyph depicts two arrowheads on a single shaft pointing to the right, and it is used in various contexts to indicate direction, mapping, or a dual-flow relationship in diagrams and mathematical notation.

Encoding and representations extend across common text encodings. The Unicode code point U+21A0 has a decimal value of 8608. In UTF-8, U+21A0 is encoded as the three-byte sequence E2 86 A0. In UTF-16, it is represented by a single 16-bit code unit 0x21A0, and in UTF-32 it is 0x000021A0.

Usage of the Rightwards Two-Headed Arrow is generally confined to technical writing, typesetting, and digital interfaces that require a symbol to convey bidirectional emphasis or flow in a single rightward direction. It is less common in ordinary prose but appears in technical diagrams, schematic representations, and some mathematical or computer-science contexts.

As with other Unicode symbols, rendering depends on the font and rendering engine. Some fonts may approximate the symbol or substitute a visually similar arrow when the exact glyph is unavailable. In programming and data interchange, the code point remains the stable reference for encoding the character across platforms.
