U+2621 "" Caution Sign Unicode Character

Unicode Version 18.0

Source: Noto Sans Math Source: Browser Default

U+2621 "" Caution Sign is a graphic symbol that represents a general warning or alert, typically depicted as an exclamation mark inside a triangle. Originally included in the Unicode standard as part of the Miscellaneous Symbols block, it is intended for use in contexts where a caution or advisory notice is needed, such as on signage, labels, or in technical documentation. While it visually resembles a hazard symbol, it is distinct from the more common "Warning Sign" (U+26A0 ⚠), as the Caution Sign often conveys a less severe level of alertness. This character allows digital text to convey a visual sense of precaution without relying on images, making it useful in plain text environments or for basic typographic warnings.
