Extended Unix Coding (EUC) is an 8-bit character encoding used primarily for Japanese and Korean. 8-bit refers to the number of bits used in the data bus of a computer. ... A character encoding is a code that pairs a set of natural language characters (such as an alphabet or syllabary) with a set of something else, such as numbers or electrical pulses. ...

In Japan, the encoding is heavily used by Unix or Unix-like operating systems, but seldom used elsewhere. It is consequently the least-used of the big 3 Japanese encodings, behind both ISO-2022-JP (JIS) and Shift-JIS. Unix or UNIX is a computer operating system originally developed in the 1960s and 1970s by a group of AT&T Bell Labs employees including Ken Thompson, Dennis Ritchie, and Douglas McIlroy. ... In computing, an operating system (OS) is the system software responsible for the direct control and management of hardware and basic system operations. ... ISO 2022, more formally ISO/IEC 2022, is an ISO standard (equivalent to the ECMA standard ECMA-35) specifying a technique for including multiple character sets in a single character encoding. ... The title given to this article is incorrect due to technical limitations. ...

EUC-CN

EUC-CN is equivalent to GB2312 standard for simplified Chinese characters. GB2312 is the registered internet name for the official character set of the Peoples Republic of China. ... Simplified Chinese characters (Simplified Chinese: 简体字; Traditional Chinese: 簡體字; pinyin: jiǎntǐzì; also called 简化字/簡化字, jiǎnhuàzì) are one of two standard character sets of printed contemporary Chinese written language. ...

EUC-JP

In the EUC-JP coding for Japanese, the 7-bit values used in ISO-2022-JP are simply incremented by 128. This allows the easy mixing of 7-bit ASCII and 8-bit Japanese without the need for the escape characters employed by ISO-2022-JP.

EUC-KR

EUC-KR is a similar 8-bit coding of ISO-2022-KR (KS X 1001), implemented with the same principle of simply adding 128 to each byte.

EUC-TW

EUC-TW is a rarely used encoding for traditional Chinese characters as used on Taiwan. Big5 is much more common. Traditional Chinese characters are one of two standard character sets of printed contemporary Chinese written language. ... For other uses, see big five (disambiguation). ...
