U2191

U+2191, commonly written as U2191 in Unicode notation, is the UPWARDS ARROW character (↑). It is part of the Unicode Arrows block, which runs from U+2190 to U+21FF. The symbol's Unicode name is UPWARDS ARROW, and its code point in decimal is 8593. In Unicode data it is categorized as a math symbol (Sm), and it is designed for use as a directional glyph in text, diagrams, and mathematical notation.

The upward arrow is used to indicate direction or movement toward a higher value in mathematical expressions and charts. It can also represent ascent, increase, or progression in various technical contexts. In user interfaces, arrows of this general shape are sometimes employed to suggest expansion, navigation to a higher item, or scrolling upward, though specific UI conventions may vary and other arrow variants (such as double arrows) can carry different meanings.

Encoding and representation on systems and platforms are straightforward since U+2191 is widely supported in modern fonts and Unicode-enabled software. It can be inserted via Unicode input methods (for example, typing the code point 2191 and applying the Unicode input), by HTML using the numeric character reference ↑ or the named entity ↑, or by copy-pasting the glyph from a character map.

Related characters include U+2190 LEFTWARDS ARROW, U+2192 RIGHTWARDS ARROW, U+2193 DOWNWARDS ARROW, and U+21D1 UPWARDS DOUBLE ARROW, among others. These symbols collectively form a family used for directional and relational notation across mathematics, science, and digital interfaces.
