Name:
	ISO2022::JUNETCompatible
ShortDescription:
	An Encode module of 7-bit ISO/IEC 2022
	based compatible coding systems for Japanese
POD:DESCRIPTION:
	Due to the historical reason, some of current
	implementions of JIS coded character sets support
	pairs of same characters dupplicately, with
	halfwidth/fullwidth property.
	
	Although this situation is undesirable, we can't ignore
	such historical implementions and latest JIS coded
	character set standards admire such dupulicate
	encoding to and only to "keep compatibility with
	current practice."
	
	This module provides encoder and decoder for such
	coding systems that comform to JIS and that based
	on 7-bit ISO/IEC 2022 structure.
	
	Those coding systems SHOULD not be used for new
	implemention or new data.  They may not comform
	to future version of JIS or other standards.

Description:
	ISO/IEC 2022 based 7-bit encoding for Japanese,
	ASCII + JIS X 0201 + JIS X 0208-1978 + JIS X 0208-1983.
	Some characters defined in JIS X 0208 are mapped to FULLWIDTH
	area of UCS as specified in JIS X 0208:1997.
	
	This encoding is a "compatible" version of
	C<iso-2022-jp> defined in Encode::ISO2022::JUNET.
	
	When decoding, mapping tables from coded character
	sets listed below to UCS are also loaded to restore
	incorrectly labeled data.
	
		JIS X 0201 Katakana coded character set,
		JIS X 0212-1990, JIS X 0213:2000
	
	Note that for Windows user, Encode::ISO2022::CP932
	may be useful to try to restore broken "ISO-2022-JP"
	data.
