Name:
	SJIS::JIS
ShortDescription:
	The Encode module for shift JIS coding systems
Description:
	This module defines convertion between perl internal
	representation and shift JIS coding systems defined
	in standards of JIS (Japan Industrial Standards).

	shift_jisx0213
Alias:

Description:
	"Shift JIS" coding system.
	
	Since this name is ambiguous (it can now refer all or any
	of shift JIS coding system family), this name should not
	be used to address specific coding system.  In this module,
	this is considered as an alias name to the shift JIS with
	latest official definition, currently of JIS X 0213:2000
	Appendix 1 (with implemention level 4).
	
	Note that the name "Shift_JIS" is not associated with
	this name, because IANA registry [IANAREG] assignes
	it to a shift JIS defined by JIS X 0208:1997.

{
AliasOf:
	shift_jisx0213-ascii
Alias:
	sjis-ascii shift-jis-ascii
Description:
	Same as sjis but ASCII (ISO/IEC 646 IRV) instead of
	JIS X 0201 Roman (or Latin) set.
	
	In spite of the history of shift JIS, ASCII is sometimes
	used instead of JIS X 0201 Roman set, because of compatibility
	with ASCII world.

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

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