What it is and where it’s used: Arabic Letter Reh is part of the Symbols family (block: Arabic). If you need styled or decorative alternatives, try our Fancy Text tool to generate compatible text that works in most modern interfaces.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+631
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.
