Code page 895

Last updated

Code page 895 (CCSID 895) [1] is a 7-bit character set and is Japan's national ISO 646 variant. [2] It is the Roman set (first or left half) of the JIS X 0201 (formerly JIS C 6220) Japanese Standard and is variously called Japan 7-Bit Latin, [3] JISCII, [4] JIS Roman, [5] JIS C6220-1969-ro, ISO646-JP [6] or Japanese-Roman. [7] Its ISO-IR registration number is 14. [8]

Amongst IBM's code pages, it accompanies code page 896 (half-width katakana), which encodes the Kana set of JIS X 0201 with extensions, and code page 897 which encodes the 8-bit form of JIS X 0201. It is used in Unix-like systems and, when combined with code page 896 and the 2-byte IBM code page 952 and code page 953, makes up the four code-sets of code page 954, one of IBM's versions of EUC-JP.

ISO/IEC 646 is the name of a set of ISO standards, described as Information technology — ISO 7-bit coded character set for information interchange and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived.

In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte.

ISO/IEC 8859-11:2001, Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 2001. It is informally referred to as Latin/Thai. It is nearly identical to the national Thai standard TIS-620 (1990). The sole difference is that ISO/IEC 8859-11 allocates non-breaking space to code 0xA0, while TIS-620 leaves it undefined.

ISO/IEC 8859-7:2003, Information technology — 8-bit single-byte coded graphic character sets — Part 7: Latin/Greek alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as Latin/Greek. It was designed to cover the modern Greek language. The original 1987 version of the standard had the same character assignments as the Greek national standard ELOT 928, published in 1986. The table in this article shows the updated 2003 version which adds three characters. Microsoft has assigned code page 28597 a.k.a. Windows-28597 to ISO-8859-7 in Windows. IBM has assigned code page 813 to ISO 8859-7. (IBM CCSID 813 is the original encoding. CCSID 4909 adds the euro sign. CCSID 9005 further adds the drachma sign and ypogegrammeni.)

In computing, JIS encoding refers to several Japanese Industrial Standards for encoding the Japanese language. Strictly speaking, the term means either:

ISO/IEC 2022Information technology—Character code structure and extension techniques, is an ISO standard specifying:

Extended Unix Code (EUC) is a multibyte character encoding system used primarily for Japanese, Korean, and simplified Chinese.

KOI8-U is an 8-bit character encoding, designed to cover Ukrainian, which uses a Cyrillic alphabet. It is based on KOI8-R, which covers Russian and Bulgarian, but replaces eight box drawing characters with four Ukrainian letters Ґ, Є, І, and Ї in both upper case and lower case.

IBM code page 932 is one of IBM's extensions of Shift JIS. The coded character sets are JIS X 0201:1976, JIS X 0208:1983, IBM extensions and IBM extensions for IBM 1880 UDC. It is the combination of the single-byte Code page 897 and the double-byte Code page 301. Code page 301 is designed to encode the same repertoire as IBM Japanese DBCS-Host.

JIS X 0201 Japanese single byte character encoding

JIS X 0201, a Japanese Industrial Standard developed in 1969, was the first Japanese electronic character set to become widely used. It is either a 7-bit encoding or an 8-bit encoding, although the 8-bit form is dominant for modern use. The full name of this standard is 7-bit and 8-bit coded character sets for information interchange (7ビット及び8ビットの情報交換用符号化文字集合).

JIS X 0212 is a Japanese Industrial Standard defining a coded character set for encoding supplementary characters for use in Japanese. This standard is intended to supplement JIS X 0208. It is numbered 953 or 5049 as an IBM code page.

JIS X 0208 is a 2-byte character set specified as a 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 7-bit and 8-bit double byte coded KANJI sets for information interchange. 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.

Microsoft Windows code page 932, also called Windows-31J amongst other names, is the Microsoft Windows code page for the Japanese language, which is an extended variant of the Shift JIS Japanese character encoding. It contains standard 7-bit ASCII codes, and Japanese characters are indicated by the high bit of the first byte being set to 1. Some code points in this page require a second byte, so characters use either 8 or 16 bits for encoding.

Code page 942 is one of IBM's extensions of Shift JIS. The coded character sets are JIS X 0201, JIS X 0208, IBM extensions for IBM 1880 UDC and IBM extensions. It is the combination of the single-byte Code page 1041 and the double-byte Code page 301.

The German standard DIN 66003, also known as Code page 1011 by IBM, Code page 20106 by Microsoft and D7DEC by Oracle, is a modification of 7-bit ASCII with adaptations for the German language, replacing certain symbol characters with umlauts and the eszett. It is the German national version of ISO/IEC 646, and also a localised option in DEC's National Replacement Character Set (NRCS) for their VT220 terminals.

Code page 1101, also known as CP1101, is an IBM code page number assigned to the UK variant of DEC's National Replacement Character Set (NRCS). The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation. Similar but not identical to the series of ISO 646 character sets, the character set is a close derivation from ASCII with only code point 0x23 differing.

Code page 897 is IBM's implementation of the 8-bit form of JIS X 0201. It includes several additional graphical characters in the C0 control characters area, and the code points in question may be used as control characters or graphical characters depending on the context, similarly in concept to OEM-US, but with different graphical characters. The C0 rows are shown below.

Code page 896, called Japan 7-Bit Katakana Extended, is IBM's code page for code-set G2 of EUC-JP, a 7-bit code page representing the Kana set of JIS X 0201 and accompanying Code page 895 which corresponds to the lower half of that standard. It encodes half-width katakana.

Code page 903 is encoded for use as the single byte component of certain simplified Chinese character encodings. It is used in China. Despite this, it follows ISO 646-JP / the Roman half of JIS X 0201, in that it replaces the ASCII backslash 0x5C with the yen/yuan sign. It also uses the same C0 replacement graphics as code page 897. When combined with the double-byte Code page 928, it forms the two code-sets of IBM code page 936.

Several mutually incompatible versions of the Extended Binary Coded Decimal Interchange Code (EBCDIC) have been used to represent the Japanese language on computers, including variants defined by Hitachi, Fujitsu, IBM and others. Some are variable-width encodings, employing locking shift codes to switch between single-byte and double-byte modes. Unlike other EBCDIC locales, the lowercase basic Latin letters are often not preserved in their usual locations.
