NAME
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 formats. 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 converters 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 representation.
