0x21C7

0x21C7 is a hexadecimal numeric value that is commonly encountered in computing and data encoding. In many contexts it represents the Unicode code point U+21C7, which sits in the Unicode Arrows block (ranging roughly from U+2190 to U+21FF). The decimal equivalent of 0x21C7 is 8647. As a code point, its visual appearance depends on the font and rendering system in use, so the exact glyph can vary between platforms.

In Unicode and text processing, codes like U+21C7 denote a specific character used for arrows in mathematical notation, diagrams, or related interfaces. Because fonts differ, some environments may render the corresponding symbol more prominently or in a style consistent with other arrows, while others may defer to a default or missing glyph. The character is not an ASCII control or printable character in the standard Latin set; it is part of a broader set of symbols used for technical notation.

Usage in software and markup is straightforward. In source code, 0x21C7 is a hexadecimal literal that can be used as a numeric value or as a code point in escapes, depending on the language. In many languages you can represent the character directly with a Unicode escape such as \u21C7 or \U000021C7, or in HTML via the hexadecimal character reference ⇇. When handling text data, normalization and font support determine whether the symbol is displayed as intended.
