What is the Unicode codepoint for the warning symbol?

The plain-text warning sign (⚠) is U+26A0. The emoji-presentation warning sign (⚠️) adds the variation selector U+FE0F after it.

What is the HTML entity for a warning symbol?

Use ⚠ for the warning sign (⚠). There is no widely supported named HTML entity for it, so the numeric entity is the safest choice.

How do I type a warning symbol on Windows?

Hold Alt and type 9888 on the numeric keypad, or use the Windows emoji panel (Win + .) and search "warning".

How do I type a warning symbol on Mac?

Open Character Viewer with Control + Command + Space and search "warning", then double-click the symbol to insert it.

Why does the warning symbol look different on some sites?

Whether it renders as a plain black-and-white sign or a colored emoji triangle depends on the font and the variation selector, not on the underlying codepoint.

Is the warning symbol the same as the caution sign used on roads?

They share the same triangle shape, but the road sign is a graphic, not a Unicode character. The Unicode warning sign is text that renders in the surrounding font or emoji set.
