ASCII 47 — /

The forward slash (solidus) is the path separator in Unix file systems, URLs, and most web technologies. In programming, '/' is the division operator. In HTML and XML, '/' appears in closing tags (</div>) and self-closing tags (<br />). The distinction between forward slash '/' and backslash '\' is a persistent source of confusion, particularly between Unix (/) and Windows (\) file path conventions. The double slash '//' marks single-line comments in C++, JavaScript, Java, and many other C-family programming languages.

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, Slash is assigned code point 47 in decimal (0x2F hexadecimal, 057 octal, 00101111 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 Slash works reliably across all operating systems, programming languages, and internet protocols.
