NAME

       eucJP - A character encoding system (codeset) for Japanese

DESCRIPTION

       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  repre-
       sents 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
       The  representation  of	ASCII/JIS Roman and JIS X0208 characters in the Japanese EUC codeset is similar to how those characters are repre-
       sented 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
       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 out-
       put, see the reference page specified in the list item.	deckanji_eucJP, eucJP_deckanji

	      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 con-
	      verters to convert Japanese text from and to Japanese code-page format. See code_page(5) for more information about how the  operat-
	      ing system supports PC code pages.  sdeckanji_eucJP, eucJP_sdeckanji

   Japanese EUC Fonts
       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  printer-resident	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.
