History & usage: The character DOWNWARDS ARROW WITH DOUBLE STROKE, U+21DF, is part of the Arrows block in the Common script. In many designs it helps users move or indicate motion downward. The symbol also serves as a visual cue in manuals and on screens. In practice, arrows commonly indicate direction and navigation cues in interfaces and documents. This helps readers follow steps or locate options. The double-stroke style adds emphasis and can suggest a stronger or more deliberate movement than a single arrow. When used in layouts, the symbol can point to next sections, scroll areas, or collapsible content. It is chosen to stand out against text and icons without adding text. Designers use it alongside other arrows to show flow, feedback, and control. Because it is a standard shape, it tends to be recognizable across languages and platforms. The guidance for its use is simple: place it where a downward action is expected and where space allows for quick scanning by the user. This makes navigation clearer and more efficient for readers.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+21DF 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.
