A character set is a collection of elements used to represent text. [9] [10] For example, the Latin alphabet and Greek alphabet are both character sets. A coded character set is a character set mapped to a set of unique numbers. [10] For historical reasons, this is also often referred to as a code page. [9]
In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference: &name;
The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers, including Unicode which has over a million code points, but the first 128 of these are the same as ASCII.
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set.The Universal Coded Character Set, most commonly called the Universal Character Set (abbr. UCS, official designation: ISO/IEC 10646), is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other ...
Writing systems are used to record human language, and may be classified according to certain common features.. The usual name of the script is given first; the name of the languages in which the script is written follows (in brackets), particularly in the case where the language name differs from the script name.
In Unicode Lookup, one enters a search key (e.g. "fractions"), and a list of corresponding characters with their code points is returned. In Shapecatcher, based on Shape context, one draws the character in a box and a list of characters approximating the drawing, with their code points, is returned.
The category of character sets includes articles on specific character encodings (see the article for a precise definition). It includes those used in computer science (coded character sets (also known as character sets (this term should not be used anymore [according to whom?]) or code pages), character encoding forms, character encoding schemes) and those that use non-numeric, pre-digital ...
