x21D5

x21D5 is a hexadecimal notation commonly used to refer to the Unicode code point U+21D5. This code point resides in the Arrows block of Unicode and represents a single graphical symbol whose exact appearance depends on the font. In typographic contexts, it is treated as a directional arrow character and is used in mathematical notation, diagrams, and user interface text where an arrow-like glyph is required.

Encoding and character references: In Unicode, the point is U+21D5. In HTML, it can be represented as the numeric character reference ⇕ or decimal reference ⇕. In most programming languages and libraries, it can be included using a Unicode escape such as \u21D5 or similar notation, depending on the language.

Rendering and fonts: The glyph rendering of U+21D5 varies by font and environment. Some fonts may depict it as a standard arrow or as a variant of an arrow used to indicate direction or relation. Because of this, visual consistency may vary across platforms.
