eucJP - A character encoding system (codeset) for Japanese
The Japanese EUC (Extended UNIX Code), or eucJP, codeset
consists of the following character sets: CS0 (ASCII or
JIS Roman) CS1 (JIS X0208) CS2 (JIS Katakana) CS3 (JIS
X0212)
CS0 is a primary character set. CS1, CS2, and CS3 are supplementary
character sets. The MSB (Most Significant Bit)
of the byte that represents a character in CS0 is set off,
whereas the MSB of the bytes that represent characters in
CS1, CS2, and CS3 is set on.
Japanese EUC Encoding [Toc] [Back]
The representation of ASCII/JIS Roman and JIS X0208 characters
in the Japanese EUC codeset is similar to how those
characters are represented in the DEC Kanji codeset (refer
to deckanji(5)). The two additional character sets, JIS
Katakana and JIS X0212, are encoded in the Japanese EUC
codeset by making use of the SS2 (Single Shift 2) and SS3
(Single Shift 3) control characters.
The Japanese EUC codeset provides the following two areas
for representation of user-defined characters (UDC):
-----------------------------------------------------------
Area Usage Row Range Number of Char- Code Range
acters
-----------------------------------------------------------
JIS X0208 85-94 940 F5A1-FEFE
JIS X0212 78-94 1598 SS3 [EEA1-FEFE]
-----------------------------------------------------------
The representation of UDCs on these two code planes is
identical to that for standard characters that occupy the
same planes. Code ranges distinguish between UDCs and
standard JIS X0208 and JIS X0212 characters that occupy
the same plane.
Currently, the operating system does not support JIS X0212
(JIS Supplementary) characters.
Codeset Conversion [Toc] [Back]
The following codeset converter pairs are available for
converting Japanese characters between eucJP and other
encoding formats. Refer to iconv_intro(5) for an introduction
to codeset conversion. For more information about
the other codeset for which eucJP is the input or output,
see the reference page specified in the list item. deckanji_eucJP,
eucJP_deckanji
Converting from and to the DEC Kanji codeset: deckanji(5). ISO-2022-JP_eucJP, eucJP_ISO-2022-JP
Converting from and to the ISO 2022 Japanese codeset:
iso2022jp(5). ISO-2022-JPext_eucJP,
eucJP_ISO-2022-JPext
Converting from and to the ISO 2022 Japanese
Extended codeset: iso2022jp(5). JIS7_eucJP,
eucJP_JIS7
Converting from and to the JIS7 codeset:
jiskanji(5). SJIS_eucJP, eucJP_SJIS
Converting from and to the Shift JIS codeset:
SJIS(5).
Shift JIS encoding is identical to the encoding
used in the Microsoft PC code page for Japanese.
You can therefore use these converters to convert
Japanese text from and to Japanese code-page format.
See code_page(5) for more information about
how the operating system supports PC code pages.
sdeckanji_eucJP, eucJP_sdeckanji
Converting from and to the Super DEC Kanji codeset:
sdeckanji(5). UTF-16_eucJP, eucJP_UTF-16
Converting from and to UTF-16 format: Unicode(5).
UCS-4_eucJP, eucJP_UCS-4
Converting from and to UCS-4 format: Unicode(5).
UTF-8_eucJP, eucJP_UTF-8
Converting from and to UTF--8 format: Unicode(5).
Japanese EUC Fonts [Toc] [Back]
For display devices, the operating system supports
Japanese EUC characters by converting Japanese EUC code to
DEC Kanji code and then using the fonts for DEC Kanji.
Because the CS3 character set is not supported by the DEC
Kanji codeset, CS3 characters cannot be displayed.
The operating system does not provide PostScript fonts for
Japanese EUC. Some printers support Japanese with printerresident
fonts and print filters perform codeset conversion,
if required, for the encoding used in the file input
to the print job. For some other printers, you can set up
a print filter to convert Japanese bitmap fonts to
PostScript. Refer to i18n_printing(5) for introductory
information about your printing options.
