Caret is the name for the symbol ^ in ASCII and some other character sets. Its Unicode code point is U+005E, and its ASCII code in hexadecimal is 5E. Strictly speaking, the caret character in common use is actually referred to in the Unicode standard as the "CIRCUMFLEX ACCENT"; the Unicode character named "CARET" is actually a distinct, much less common character, at code point U+2038 . There is also a combining mark, U+0302 "COMBINING CIRCUMFLEX ACCENT", which is used when a circumflex accent is to be added as a diacritical mark to another letter. However, the term "caret" is most frequently used to refer to the first of these.

The circumflex (ˆ) (often also called a "caret", from a non-diacritical sign with similar shape (^); also "hat" or "uppen") is a diacritic mark used in written Greek, French, Frisian, Esperanto,  Norwegian, Romanian, Slovak, Vietnamese, Romanized Japanese, Welsh, Portuguese, Italian, Afrikaans, Turkish and other languages. It received its English name from Latin circumflexus (bent about)—a translation of the Greek περισπωμένη (perispomeni).
