2     Name:
3     SJIS::JIS
4     ShortDescription:
5     The Encode module for shift JIS coding systems
6     Description:
7     This module defines convertion between perl internal
8     representation and shift JIS coding systems defined
9     in standards of JIS (Japan Industrial Standards).

12 wakaba 1.2 AliasOf:
13     shift_jisx0213
14     Alias:
15     sjis s-jis x-sjis x_sjis x-sjis-jp shift-jis shiftjis shift.jis x-shiftjis x-shift-jis x-shift_jis
16     Description:
17     "Shift JIS" coding system.
18    
19     Since this name is ambiguous (it can now refer all or any
20     of shift JIS coding system family), this name should not
21     be used to address specific coding system. In this module,
22     this is considered as an alias name to the shift JIS with
23     latest official definition, currently of JIS X 0213:2000
24     Appendix 1 (with implemention level 4).
25    
26     Note that the name "Shift_JIS" is not associated with
27     this name, because IANA registry [IANAREG] assignes
28     it to a shift JIS defined by JIS X 0208:1997.

32     AliasOf:
33     shift_jisx0213-ascii
34     Alias:
35     sjis-ascii shift-jis-ascii
36     Description:
37     Same as sjis but ASCII (ISO/IEC 646 IRV) instead of
38     JIS X 0201 Roman (or Latin) set.
39    
40     In spite of the history of shift JIS, ASCII is sometimes
41     used instead of JIS X 0201 Roman set, because of compatibility
42     with ASCII world.

63     Description:
64     Shift coded representation defined by JIS X 0208:1997 Appendix 1.
65    
66     Note that although IANA registry [IANAREG] assignes the name "MS_Kanji"
67     as an alias of "Shift_JIS", in this module this name is not aliased
68     for the shift-coded representation of JIS X 0208, since it is more
69     apropreate to associate this name with
70     Microsoft-defined-Shift-JIS. (Microsoft's shift JIS is a superset of
71     "shifted" form of JIS X 0208-1990, so it causes no problem to decode,
72     despite MS Shift JIS does not comform to JIS X 0208:1997.)

172     POD:ENCODING:POSTAMBLE:
173     Shift JISes using alternative character names defined
174     by JIS X 0208:1997 or JIS X 0213:2000 (so some characters
175     are mapped to HALFWIDTH or FULLWIDTH area of UCS) are not
176     included in this module but in L<Encode::SJIS::JISCompatible>.
177    
178     Shift JISes with JIS X 0208-1978, -1983, -1990 are not
179     included in this module since these standards did NOT
180     define them (but some vendor did implement them as non-standard
181     encodings). They are defined in Encode::SJIS::* modules
182     other than this.
183    
184     Being ones of Shift JISes defined in *JIS* TR, Shift JIS
185     variants defined by JIS TR X 0015 "XML Japanese profile"
186     is not supported by this module, but by other Encode::SJIS::*
187     modulss. Shift JISes which is given their names by JIS TR X 0015
188     are all vendor defined variants of Shift JISes and do NOT part
189     of formal JIS coded character set standards NOR comform to
190     those standards. (It might sound strange that JIS TR defines
191     names for encodings clealy not comforming to JIS standards.
192     JIS TR "standalization" process is much looser than JIS standard's.)
