As of Unicode version 16.0, there are 155,063 characters with code points, covering 168 modern and historical scripts, as well as multiple symbol sets. This article includes the 1,062 characters in the Multilingual European Character Set 2 ( MES-2 ) subset, and some additional related characters.
This list provides an inventory of character coding standards mainly before modern standards like ISO/IEC 646 etc. Some of these standards have been deeply involved in historic events that still have consequences. One notable example of this is the ITA2 coding used during World War II (1939–1945).
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 ...
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]
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 ...
The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented writing systems are added.
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
The term DBCS traditionally refers to a character encoding where each graphic character is encoded in two bytes.. In an 8-bit code, such as Big-5 or Shift JIS, a character from the DBCS is represented with a lead (first) byte with the most significant bit set (i.e., being greater than seven bits), and paired up with a single-byte character-set (SBCS).
