shiftjis, SJIS - A character encoding system (codeset) for Japanese DESCRIPTION
The Shift JIS (SJIS) codeset consists of the following character sets: JIS X0201 JIS X0208 User-Defined Characters (UDC) Shift JIS Encoding 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. Font Support for Super DEC Kanji For display devices, the operating system supports Super DEC Kanji encoding by conversion to DEC Kanji encoding and then using fonts avail- able 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. For general information on printing non-English text, refer to i18n_printing(5). SEE ALSO

jiskanji, jiskanji7, JIS7 - A character encoding system (codeset) for Japanese DESCRIPTION
JIS Kanji is a codeset that uses the JIS X0202 symbol extension method for encoding the JIS X0208 and JIS X0201 character sets. There are two types of JIS Kanji encoding: 7-bit JIS Kanji code and 8-bit JIS Kanji code. 7-bit JIS Kanji Code In 7-bit JIS Kanji encoding, all character values are 7-bit bytes. Characters are interpreted according to preceding in and out sequences as follows: Kanji in sequence (ESC $ B) The code values following the Kanji in sequence (ESC $ B) are treated as characters in the JIS X0208 Kanji character set. Kanji out sequence (ESC ( B) The code values following the Kanji out sequence (ESC ( B) are treated as ASCII characters. Supplementary Kanji in sequence (ESC $ ( D) The code values following the supplementary Kanji in sequence (ESC $ ( D) are treated as characters in the JIS X0212 supplementary Kanji character set. User-Defined Character (UDC) in sequence (ESC $ ( 0) The code values following the UDC in sequence (ESC $ ( 0) are treated as characters in the vendor-defined or user-defined character set. Kana in (SO) and Kana out (SI) sequences The code values following SO(0x0e) and preceding SI(0x0f) are treated as characters in the JIS X0201 Katakana character set. Katakana in sequence (ESC ( I) Code values following the Katakana in sequence (ESC ( I) are treated as characters in the JIS X0201 Katakana character set. In this case, the Kanji out sequence is used to switch back to ASCII code. The Katakana in and Kanji out sequences are an alternative to using the Kana in and out sequences (SO/SI). 8-bit JIS Kanji Code In 8-bit JIS Kanji encoding, the JIS X0201 Katakana characters are represented as 8-bit bytes. Using this form of encoding, in and out sequences have the following effect: Kanji in sequence (ESC $ B) Code values following the Kanji in sequence (ESC $ B) are treated as characters in the JIS X0208 Kanji character set. Supplementary Kanji in sequence (ESC $ ( D) Code values following the supplementary Kanji in sequence (ESC $ ( D) are treated as characters in the JIS X0212 supplementary Kanji character set. User-Defined Character (UDC) in sequence (ESC $ ( 0) Code values following the UDC in sequence (ESC $ ( 0) are treated as vendor-defined or user-defined characters. Kanji out sequence (ESC ( B) Code values following the Kanji out sequence (ESC ( B) are treated as ASCII characters. Kana in and out sequences (SI/SO) These sequences are ignored. Codeset Conversion The following codeset converter pairs are available for converting Japanese characters between jiskanji7 or JIS7 and other encoding for- mats. The RESTRICTIONS section discusses some conversion limitations that apply to these converters. Refer to iconv_intro(5) for an introduction to codeset conversion. For more information about the other codeset for which jiskanji7 or JIS7 is the input or output, see the reference page specified in the list item. deckanji_jiskanji7 or deckanji_JIS7, jiskanji7_deckanji or JIS7_deckanji Converting from and to the DEC Kanji codeset: deckanji(5). eucJP_jiskanji7 or eucJP_JIS7, jiskanji7_eucJP or JIS7_eucJP Converting from and to Japanese Extended UNIX Code: eucJP(5). eucTW_jiskanji7 or eucTW_JIS7, jiskanji7_eucTW or JIS7_eucTW Converting from and to Taiwanese Extended UNIX Code: eucTW(5). sdeckanji_jiskanji7 or sdeckanji_JIS7, jiskanji7_sdeckanji or JIS7_sdeckanji Converting from and to the Super DEC Kanji codeset: sdeckanji(5). SJIS_jiskanji7 or SJIS_JIS7, jiskanji7_SJIS or JIS7_SJIS Converting from and to Shift JIS format: SJIS(5). Shift JIS encoding format is identical to encoding in Microsoft code-pages used on PC systems. Therefore, you can use these convert- ers to convert Japanese characters between JIS Kanji and PC code-page format. For general information on how the operating system supports PC code pages, see code_page(5). RESTRICTIONS
The JIS Kanji codeset is not supported directly by a locale but through code conversion (through the iconv utility, Japanese terminal (tty) code conversion, and so forth). In the codeset naming conventions used by the iconv utility, the string JIS7 indicates 7-bit JIS Kanji code that follows a Katakana in sequence and the string jiskanji7 indicates 7-bit JIS Kanji code entered between Kana in and out sequences. The following sequences are valid for input to the iconv utility but are not generated when code is converted to jiskanji7: Kanji in (ESC $ @) Kanji in (ESC & @ ESC $ B) Kanji in (ESC $ ( B) Kanji in (ESC $ ( @) Supplementary Kanji in (ESC $ D) Kana in (ESC ( J) Kana in (ESC ( H) In the code naming conventions of the Japanese terminal, the string jis7 indicates 7-bit JIS Kanji code and the string jis8 indicates 8-bit JIS Kanji code. When the terminal code is set to jis7, the Kana in and out sequences (SI/SO) are used for JIS X0201 Katakana character rep- resentation. SEE ALSO
