ISO code sets

The code sets listed in the following topics are based on definitions set by the International Organization for Standardization (ISO).

ISO646-IRV
The ISO646-IRV code set below defines the code set used for information processing based on a 7-bit encoding. The character set associated with this code set is derived from the ASCII characters.
ISO8859 family
ISO8859 is a family of single-byte encodings based on and compatible with other ISO, American National Standards Institute (ANSI), and European Computer Manufacturer's Association (ECMA) code extension techniques. The ISO8859 encoding defines a family of code sets with each member containing its own unique character sets. The 7-bit ASCII code set is a proper subset of each of the code sets in the ISO8859 family.
Code set ISO8859-1
The available symbols and the layout of code set ISO8859-1 are covered in this section.
Code set ISO8859–2
The available symbols and the layout of code set ISO8859-2 are covered in this section.
Code set ISO8859-4
The available symbols and the layout of code set ISO8859-4 are covered in this section.
Code set ISO8859-5
The available symbols and the layout of code set ISO8859-5 are covered in this section.
Code set ISO8859–6
The available symbols and the layout of code set ISO8859-6 are covered in this section.
Code set ISO8859–7
The available symbols and the layout of code set ISO8859-7 are covered in this section.
Code set ISO8859–8
The available symbols and the layout of code set ISO8859-8 are covered in this section.
Code set ISO8859–9
The available symbols and the layout of code set ISO8859-8 are covered in this section.
Code set ISO8859–15
The available symbols and the layout of code set ISO8859-15 are covered in this section.
Extended UNIX code (EUC) encoding scheme
The EUC encoding scheme defines a set of encoding rules that can support one to four character sets. The encoding rules are based on the ISO2022 definition for the encoding of 7-bit and 8-bit data. The EUC encoding scheme uses control characters to identify some of the character sets. The following table shows the basic structure of all EUC encoding.
IBM-eucJP
The EUC for Japanese is an encoding consisting of single-byte and multibyte characters. The encoding is based on ISO2022, Japanese Industrial Standard (JIS), and EUC definitions.
IBM-eucCN
The EUC for the Simplified Chinese language is an encoding consisting of characters that contain 1 or 2 bytes. The EUC encoding is based on ISO2022, GB2312 as defined by the People's Republic of China, and multibyte character definitions unique to the manufacturer.
GB18030
GBK stands for Guo (national) Biao (Standard) Kuo (Extension). GB18030 expands the national "Industry GB" definition to contain all 20, 902 Han Characters defined in Unicode and additional DBCS symbols defined in Big-5 code (Traditional Chinese PC defacto standard). GB18030 defines all DBCS characters and symbols in use in mainland China and in Taiwan.
IBM-eucTW
The EUC for the Traditional Chinese language is an encoding consisting of characters that contain 1, 2 and 4 bytes. The EUC encoding is based on ISO2022, the Chinese National Standard (CNS) as defined by Taiwan, and multibyte character definitions unique to the manufacturer.
Big5
The Traditional Chinese big5 locale, Zh_TW, code set is the most commonly used code set in the PC field that is used to support countries using Traditional Chinese.
IBM-eucKR
The EUC for the Korean language is an encoding consisting of single-byte and multibyte characters. The encoding is based on ISO2022, Korean Standard Code set, and EUC definitions.
