DESCRIPTION

48       To find out how to use this module in detail, see Encode.
49
50   Notes on Compatibility
51       To encode Unicode string to byte string, "x-iso2022jp2004-strict" uses
52       JIS X 0208 as much as possible, strictly conforming to JIS X 0213:2004
53       Annex 2.  It is compatible to other encodings.
54
55       "x-iso2022jp2004-compatible" uses JIS X 0208 for the bit combinations
56       co-existing on JIS X 0208 and JIS X 0213 plane 1.  It is not compatible
57       to other encodings; it had never been registered by any standards
58       bodies.
59
60       However, to decode byte string to Unicode string, encodings in the
61       tables above accept arbitrary sequences of both JIS X 0208 and JIS X
62       0213.  Exception is "x-iso2022jp2004-strict": It accepts only allowed
63       JIS X 0208 sequences.
64
65       "euc-jis-2004" and "euc-jisx0213" contains JIS X 0213 plane 2 along
66       with JIS X 0212 in G3.  By this non-standard extension, they have
67       forward compatibility with EUC-JP (AJEC) in case of decoding.
68
69   Comparison with Other Modules
70       Encode::JIS2K provides "euc-jisx0213", "iso-2022-jp-3" and
71       "shift_jisx0213" encodings.  "euc-jp" in Encode::JP 1.64 or later can
72       decode "euc-jisx0213" sequences.  They support earlier revision of
73       standard, and lack function to encode sequences with multiple Unicode
74       characters such as katakana with semi-voiced sound mark.
75
76       ShiftJIS::X0213::MapUTF provides "shift_jisx0213" and "shift_jis-2004".
77       It does not provide interface to contemporary Encode module.
