A character set maps a set of characters to specific numeric values.

Modern computer languages, editors and tools facilitate encoding and decoding of data between internal representations of data and specific character sets. Examples include ASCII, UTF-8 and ISO-8859-1.

Consideration should be given to using the appropriate character set for transmission and persistence of data, particularly text that can contain special characters (such as European languages like French or German) or be in a completely different script (such as Japanese) - see internationalisation (also referred to as i18n).
