Shift JIS is the third-most declared character encoding for Japanese websites, used by 1.0% of sites in the .jp domain, while UTF-8 is used by 99% of Japanese websites. [5] [6] Shift JIS is also sometimes used in QR codes (they are a Japanese invention also allowing UTF-8, which may though be preferred use). [7] [8]
In practice, "JIS encoding" usually refers to JIS X 0208 character data encoded with JIS X 0202. For instance, the IANA uses the JIS_Encoding label to refer to JIS X 0202, and the ISO-2022-JP label to refer to the profile thereof defined by RFC 1468. [2] Other encoding mechanisms for JIS characters include the Shift JIS encoding and EUC-JP.
In 1982, the Microsoft Kanji encoding scheme (Codepage 932 of MS-DOS) and Digital Research's SJC26 (for Japanese CP/M-86) were developed to combine JIS X 0201 single-byte encoding and JIS X 0208 double byte encoding without shift out and shift in characters. [4] They were called Shift JIS, which became the industrial standard for personal ...
Python, for example, uses the label MS-Kanji (or cp932) for Windows-932 and the label Shift_JIS (or sjis) for JIS X 0208-defined Shift JIS, without recognising the Windows-31J label. [ 12 ] In Japanese editions of Windows, this code page is referred to as "ANSI" , since it is the operating system's default 8-bit encoding, even though ANSI was ...
JIS X 0213 also defines Shift_JISx0213, a variant of Shift_JIS capable of encoding the entirety of JIS X 0213. For most intents and purposes, JIS X 0213 plane 1 is a superset of JIS X 0208. However, different unification criteria are applied to some code points in JIS X 0213 compared to JIS X 0208.
One difference is that IBM-932 encodes the JIS X 0208:1983 characters but preserves the 1978 ordering, whereas IBM-943 uses the 1983 ordering [1] (i.e. the character variant swaps made in JIS X 0208:1983). Another difference is that IBM-932 does not incorporate the NEC selected extensions, which IBM-943 includes for Microsoft compatibility. [1]
There are several standard methods to encode Japanese characters for use on a computer, including JIS, Shift-JIS, EUC, and Unicode. While mapping the set of kana is a simple matter, kanji has proven more difficult. Despite efforts, none of the encoding schemes have become the de facto standard, and multiple encoding standards were in use by the ...
JIS X 0208 is a widely deployed standard for Japanese character encoding that has several encoding forms. Shift JIS (Microsoft Code page 932 is a dialect of Shift_JIS) EUC-JP; ISO-2022-JP; JIS X 0213 is an extended version of JIS X 0208. Shift_JIS-2004; EUC-JIS-2004; ISO-2022-JP-2004; Chinese Guobiao.
