No One Under Eighteen Symbol 🔞
🔞 (U+1F51E) is a standard Unicode character that you can copy and paste anywhere text is accepted. This page provides a concise reference with safe tips, internal links, and practical guidance so you can use it reliably across apps and platforms.
What it is and where it’s used: No One Under Eighteen Symbol is part of the Symbols family (block: Miscellaneous Symbols and Pictographs). 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 character depicts the NO ONE UNDER EIGHTEEN SYMBOL. It signals age restrictions in content or spaces. Use it in messaging to flag material that is not suitable for underage audiences. It can appear in user interfaces to warn about age‑restricted settings, or in policy notes and consent screens to remind users of age limits. It also helps moderation or access control by indicating compliance requirements. Be mindful that appearance varies across platforms, apps, and fonts, so color, style, and detail may differ. For accessibility, ensure surrounding text conveys the intended meaning and provide a text alternative if needed. Across platforms, test rendering and keep the message clear for all users.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+1F51E 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.
