Warning Emoji Unicode, HTML and Shortcode Values

For developers and designers, the warning emoji ⚠️ has several standardized technical representations. This reference covers every format you're likely to need.

Unicode code point

The base character is U+26A0 (WARNING SIGN), part of the Miscellaneous Symbols block. Adding the emoji variation selector U+FE0F requests the full-color emoji-style rendering instead of the plain black-and-white text glyph.

HTML entities

In HTML, you can render the warning emoji using the decimal entity ⚠️ or the equivalent hexadecimal entity ⚠️. Both produce the identical character in a browser.

CSS content property

In CSS, the warning emoji can be inserted via a pseudo-element using content: "\26A0";, useful for adding the icon purely through stylesheets without touching markup.

Shortcode

Many chat platforms, including Slack and GitHub, support the shortcode :warning:, which automatically renders as the warning emoji without needing to type or paste the Unicode character directly.

JavaScript escape sequence

In JavaScript strings, the warning emoji can be written as "\u26A0\uFE0F", which is useful when hardcoding emoji into scripts or JSON data without relying on copy-paste.

Choosing the right format

Use the plain Unicode character for chat and social media, HTML entities for raw markup, the CSS content property for icon styling, and the shortcode wherever your platform supports it for readability in source files.
