shiftjis, SJIS - A character encoding system (codeset) for Japanese
The Shift JIS (SJIS) codeset consists of the following
User-Defined Characters (UDC)
Shift JIS character codes use a combination of single-byte data and 2-byte data to represent characters defined in the JIS X0201 and JIS X0208 standards and in the UDC area.
All JIS X0201 characters are represented in the form of single-byte data. The Roman letters in JIS X0201 are encoded by setting the most significant bit (MSB) of each byte to off, while the Katakana characters are encoded by setting the most significant bit (MSB) of each byte to on. For more information on JIS X0201 characters, refer to deckanji(5). In the Super DEC Kanji codeset, the code ranges for JIS X0201 characters are as follows: For Roman letters, 00 to 7F For Katakana characters, A1 to DF
JIS X0208 characters are encoded in 2-byte values. The values for the first bytes are encoded so that they fall outside the range of byte values for JIS X0201 characters (in other words, the JIS X0208 first byte ranges are from 81 to 9F and from E0 to FC). In this manner, characters from the two different standards can be supported by the same codeset. The range for the second byte of a JIS X0208 character is 40 to FC (except for 7F). For more information on JIS X0208 characters, refer to deckanji(5).
The Shift JIS codeset provides for 2444 UDC characters. These are encoded
as 2-byte values whose code range is F040 to FCFC.
For display devices, the operating system supports Super DEC Kanji encoding by conversion to DEC Kanji encoding and then using fonts available for DEC Kanji. Refer to the iconv_intro(5) reference page for information on codeset conversion.
For printers, the operating system supports only printer-resident fonts;
therefore, Super DEC Kanji fonts cannot be dynamically loaded to a printer.
