What it is and where it’s used: Leftwards Double Arrow is part of the Symbols family (block: Arrows). If you need styled or decorative alternatives, try our Fancy Text tool to generate compatible text that works in most modern interfaces.
History & usage: The LEFTWARDS DOUBLE ARROW is a symbol in the Arrows block of Unicode. It has the code point U+21D0 and the English name LEFTWARDS DOUBLE ARROW. It belongs to the Common script, which means it is designed for general use across languages. In plain terms, this character is drawn as two arrows pointing to the left. The name and the double arrows help differentiate it from a single leftward arrow. It appears in lists, diagrams, and interfaces where a leftward direction is important. The character is part of how people show backward movement, negation, or return in a compact form. In history and usage, designers use it to save space while conveying the idea of going back or moving left. The single symbol can replace longer phrases in captions or controls. Because it is in the Arrows block, it fits with other directional marks used by software and documents. Overall, the LEFTWARDS DOUBLE ARROW serves as a clear, portable indicator of leftward direction across contexts. It helps users understand flow, navigation, and choice with minimal text.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+21D0
in many development tools or editors. Some operating systems provide a character viewer or input palette that lets you search by name or code and insert the glyph into documents.
Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint. Switching to a font with broader Unicode coverage or using a fallback font usually fixes the issue. On the web, ensure the page’s font stack includes a general‑purpose fallback.
