Questions tagged [character]

Refers to a symbol that represents a letter or number. Also, the bit pattern used to represent such a symbol.

In computer and machine-based telecommunications terminology, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language. Examples of characters include letters, numerical digits, and common punctuation marks (such as '.' or '-'). The concept also includes control characters, which do not correspond to symbols in a particular natural language, but rather to other bits of information used to process text in one or more languages. Computers and communication equipment represent characters using a character encoding that assigns each character to something — an integer quantity represented by a sequence of bits, typically — that can be stored or transmitted through a network. Two examples of popular encodings are ASCII and the UTF-8 encoding for Unicode.
