ASCII 94 — ^

The caret (circumflex accent) has diverse and context-dependent meanings across computing. In regular expressions, '^' anchors a match to the beginning of a line, and inside character classes '[^...]' negates the class to match anything not listed. In C, Java, and JavaScript, '^' performs bitwise XOR operations. In some languages and calculators, '^' denotes exponentiation. In Markdown variants, '^' creates superscript notation. On vintage terminals, the caret combined with a letter represented control characters — '^C' for ETX, '^D' for EOT — a notation convention still used in documentation.

Symbol characters in ASCII include mathematical operators, logical notation, and special-purpose marks that serve critical roles across programming, mathematics, and digital communication. Symbols are heavily context-dependent — the same character may act as an arithmetic operator in one language, a regex metacharacter in another, and a shell configuration flag in a third context. This contextual polyvalence makes symbols among the most functionally overloaded characters in computing, requiring careful attention to their meaning in each domain.

In the ASCII encoding table, Caret is assigned code point 94 in decimal (0x5E hexadecimal, 136 octal, 01011110 binary). The 7-bit ASCII standard, first published in 1963 by the American Standards Association, defines exactly 128 characters that remain the foundation of text encoding systems worldwide. UTF-8, the dominant encoding on the modern web, is fully backward compatible with ASCII — every ASCII character is encoded as the identical single byte in UTF-8, guaranteeing that Caret works reliably across all operating systems, programming languages, and internet protocols.
