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.

80 JIS X 0213:2000 7ビット及び8ビットの2バイト情報交換用符号化拡張漢字集合
81 (7-bit and 8-bit double byte coded extended KANJI sets for information
82 interchange), and its amendment JIS X 0213:2000/Amd.1:2004.
