x21F7

x21F7 refers to the Unicode code point U+21F7, a symbol in the Unicode Arrows block. It is a directional arrow character used in text and diagrams where a specialized arrow is required. Because font glyphs vary, the exact appearance of U+21F7 can differ between fonts; some render it as a leftward arrow with a distinctive double stroke, while others may show a more stylistic variation. In practice, its glyph is determined by the font in use, and some environments may substitute a different but visually similar symbol if a dedicated glyph is unavailable.

Encoding and representation: U+21F7 is assigned the code point 21F7 in hexadecimal (8695 in decimal). In UTF-8, it is encoded as a three-byte sequence. In HTML or XML, you can represent it with a character reference such as ⇷ or ⇷.

Usage and compatibility: As with many specialized arrow symbols, rendering depends on font support. It is not among the most common symbols, so some fonts or systems may lack a dedicated glyph, resulting in fallback rendering or a placeholder. Despite this, it remains part of the standard set of arrows used for technical notation, diagrams, and UI design where a precise directional indicator is needed.

Relation and context: U+21F7 sits within the Unicode Arrows block, which contains many arrow-related symbols used across mathematics, logic, computing, and typography. Users should test rendering across platforms and fonts when precise appearance is important.
