Circumflex Accent ^

The Circumflex Accent character (^) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ^, the decimal numeric character reference ^, or the hexadecimal numeric reference ^. The character is assigned Unicode code point U+005E in the Universal Character Set.

The circumflex accent (caret) is used in programming for bitwise XOR, exponentiation in some languages, and as the start-of-line anchor in regular expressions. In markdown, it creates superscript text. The standalone caret is a spacing character, distinct from the combining circumflex used in accented letters.

Technical character entities represent brackets, delimiters, and punctuation marks that frequently require escaping in HTML source code and programming contexts. Characters like curly braces, square brackets, pipes, and backslashes often carry special meaning in templating engines, regular expressions, or markup parsers, making their explicit HTML entity encoding important for preventing unintended interpretation by the browser or build tools.

When deciding how to encode the Circumflex Accent character in your HTML documents, the named entity ^ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ^ and hexadecimal form ^ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the caret entity in technical documentation about regular expressions (where ^ anchors to the start of a line), bitwise operations, and exponentiation. In most HTML contexts, the caret can be typed directly, but the entity is useful in generated or template-processed content.
