AltKeyCodes

Caution Sign Symbol

There is no legacy Windows Alt code for Caution Sign because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+2621, which you can use as ☡ in HTML, \2621 in CSS, or type with Alt+9761 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Caution Sign is outside both legacy code pages, which is why U+2621 is the identifier that works across Word, HTML, CSS, Python and JavaScript. Caution Sign has no named HTML entity, so use the numeric escape ☡ or the hex escape ☡.
