ISO-IR
ISO/IEC 2022 ''Information technology—Character code structure and extension techniques'', is an ISO/IEC standard in the field of character encoding. It is equivalent to the ECMA standard ECMA-35, the ANSI standard ANSI X3.41 and the Japanese Industrial Standard JIS X 0202. Originating in 1971, it was most recently revised in 1994. ISO 2022 specifies a general structure which character encodings can conform to, dedicating particular ranges of bytes ( 0x00–1F and 0x7F–9F) to be used for non-printing control codes for formatting and in-band instructions (such as line breaks or formatting instructions for text terminals), rather than graphical characters. It also specifies a syntax for escape sequences, multiple-byte sequences beginning with the control code, which can likewise be used for in-band instructions. Specific sets of control codes and escape sequences designed to be used with ISO 2022 include ISO/IEC 6429, portions of which are implemented by ANSI.SYS and term ...

ISO/IEC 646
ISO/IEC 646 ''Information technology — ISO 7-bit coded character set for information interchange'', is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard in the field of character encoding. It is equivalent to the Ecma International, ECMA standard ECMA-6 and developed in cooperation with ASCII at least since 1964. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. The first edition of ISO/IEC 646 was published in 1973, and the most recent, third, edition in 1991. ISO/IEC 646 specifies a 7-bit character code from which several national standards are derived. It allocates a set of 82 unique graphic characters to 7-bit code points, known as the ''invariant'' (INV) or ''basic character set'', including letters of the ISO basic Latin alphabet, Numerical digit, digits, and some common English language, English pun ...

ISO/IEC 10367
ISO/IEC 10367:1991 is a standard developed by ISO/IEC JTC 1/SC 2, defining graphical character sets for use in character encodings implementing levels 2 and 3 of ISO/IEC 4873 (as opposed to ISO/IEC 8859, which defines character encodings at level 1 of ISO/IEC 4873). Relationship to ISO/IEC 8859 The parts of ISO/IEC 8859 define complete encodings at level 1 of ISO/IEC 4873 (i.e., as stateless extended ASCII single-byte encodings, reserving the C1 area), and do not allow for use of multiple parts together. For use at levels 2 and 3 of ISO/IEC 4873 (i.e., with shift codes for additional graphical character sets), ISO/IEC 8859 stipulates that equivalent sets from ISO/IEC 10367 should be used instead. ISO/IEC 10367:1991 includes ASCII, as well as sets matching the G1 sets used for the right-hand sides (non-ASCII parts) of ISO/IEC 6937 ( ITU T.51) and of ISO/IEC 8859 parts 1 through 9 (i.e., those parts that existed as of 1991, when it was published), a set of additional Roman cha ...

GB 2312
is a key official character set of the People's Republic of China, used for Simplified Chinese characters. GB2312 is the registered internet name for EUC-CN, which is its usual encoded form. ''GB'' refers to the Guobiao standards (国家标准), whereas the ''T'' suffix ( zh, c= 推荐, p=tuījiàn, l=recommendation, labels=no) denotes a non-mandatory standard. was originally a mandatory national standard designated . However, following a National Standard Bulletin of the People's Republic of China in 2017, GB 2312 is no longer mandatory, and its standard code is modified to . has been superseded by GBK and GB 18030, which include additional characters, but remains in widespread use as a subset of those encodings. , GB2312 is the second-most popular encoding served from China and territories (after UTF-8), with 5.5% of web servers serving a page declaring it. Globally, GB2312 is declared on 0.1% of all web pages. However, all major web browsers decode GB2312-marked document ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C0 And C1 Control Codes
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the range 00 HEX–1FHEX and the default C0 set was originally defined in ISO 646 (ASCII). C1 codes are the range 80HEX–9FHEX and the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). The ISO/IEC 2022 system of specifying control and graphic characters allows other C0 and C1 sets to be available for specialized applications, but they are rarely used. C0 controls ASCII defines 32 control characters, plus the DEL character. This large number of codes was desirable at the time, as multi-byte controls would require implementation of a state machine in the terminal, which was very difficult with contemporary electr ...

CNS 11643
The CNS 11643 character set (Chinese National Standard 11643), also officially known as the Chinese Standard Interchange Code or CSIC ( zh, tr=, t=中文標準交換碼), is officially the standard character set of Taiwan (Republic of China). Published and draft editions of CNS 11643 remain the source standards for Unicode reference glyphs for CJK Unified Ideographs submitted for use in Taiwan, and the character repertoire of CNS 11643 continues to be updated and used for administrative purposes in Taiwan. EUC-TW is an encoded representation of CNS 11643 and ASCII in Extended Unix Code (EUC) form. In practice, variants of the Big5 character set, which is closely related to the first two planes of CNS 11643, served as the ''de facto'' standard encoding for Traditional Chinese before the introduction of Unicode. Other encodings capable of representing certain CSIC planes include ISO-2022-CN (planes 1 and 2) and ISO-2022-CN-EXT (planes 1 through 7). Structure CNS 11643 is designed ...

JIS X 0208
JIS X 0208 is a 2-byte character set specified as a Japanese Industrial Standards, Japanese Industrial Standard, containing 6879 graphic characters suitable for writing text, place names, personal names, and so forth in the Japanese language. The official title of the current standard is . It was originally established as JIS C 6226 in 1978, and has been revised in 1983, 1990, and 1997. It is also called Code page 952 by IBM. The 1978 version is also called Code page 955 by IBM. Scope of use and compatibility The character set JIS X 0208 establishes is primarily for the purpose of between data processing systems and the devices connected to them, or mutually between data communication systems. This character set can be used for data processing and text processing. Partial implementations of the character set are not considered compatible. Because there are places where such things have happened as the original drafting committee of the first standard taking care to separate c ...

JIS X 0201
JIS X 0201, a Japanese Industrial Standards, Japanese Industrial Standard developed in 1969, was the first Japanese electronic character set to become widely used. The character set was initially known as JIS C 6220 before the JIS category reform. Its two forms were a 7-bit encoding or an 8-bit encoding, although the 8-bit form was dominant until Unicode (specifically UTF-8) replaced it. The full name of this standard is ''7-bit and 8-bit coded character sets for information interchange'' (). The first 96 codes comprise an ISO 646 variant, mostly following ASCII with some differences, while the second 96 character codes represent the phonetic Japanese katakana signs. Since the encoding does not provide any way to express hiragana or kanji, it is only capable of expressing simplified written Japanese. Nevertheless, this simplification can represent the full range of sounds in the language. In the 1970s, this was acceptable for media such as text mode computer terminals, telegrams, r ...
