Brain 🧠
🧠 (U+1F9E0) 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: Brain is part of the Symbols family (block: Supplemental 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 BRAIN emoji depicts a brain. It can represent thinking, intelligence, learning, or discussions of brain health in messages and interfaces. In chats, it helps show someone is thinking hard, solving a problem, or talking about science topics. In user interfaces or educational content, it signals cognitive tasks, study tips, or neuroscience themes. Its meaning depends on context, so pair it with clear text to avoid confusion. Appearance varies across platforms, apps, and fonts, so color, style, and detail may differ. If a platform lacks color emoji support, a grayscale or text-style fallback may appear. For accessibility, ensure surrounding text conveys the intended meaning and provide alt text or captions for assistive technologies.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+1F9E0 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.

Compatibility & troubleshooting
Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.
Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
