In CSS pseudo-elements use content: '\1F4A1';.
In JavaScript and TypeScript the escape '\u{1F4A1}' evaluates to 💡. In Python source, write '\U0001F4A1'.
The character encodes to F0 9F 92 A1 as UTF-8 bytes and D83D DCA1 as UTF-16 code units. Its decimal codepoint is 128161.
This is a fully-qualified emoji and should render with colour on iOS, Android, Windows and macOS. Appearance may vary between platforms, but the underlying codepoint is identical everywhere.
