| 2 | Name: |
| 3 | ISO2022::JISCompatible |
| 4 | ShortDescription: |
| 5 | An Encode module of ISO/IEC 2022 |
| 6 | based compatible coding systems for Japanese |
| 7 | POD:DESCRIPTION: |
| 8 | Due to the historical reason, some of current |
| 9 | implementions of JIS coded character sets support |
| 10 | pairs of same characters dupplicately, with |
| 11 | halfwidth/fullwidth property. |
| 12 | |
| 13 | Although this situation is undesirable, we can't ignore |
| 14 | such historical implementions and latest JIS coded |
| 15 | character set standards admire such dupulicate |
| 16 | encoding to and only to "keep compatibility with |
| 17 | current practice." |
| 18 | |
| 19 | This module provides encoder and decoder for such |
| 20 | coding systems that comform to JIS and that based |
| 21 | on ISO/IEC 2022 structure. |
| 22 | |
| 23 | Those coding systems SHOULD not be used for new |
| 24 | implemention or new data. They may not comform |
| 25 | to future version of JIS or other standards. |

| 38 | Description: |
| 39 | ISO/IEC 2022 based 7-bit encoding for Japanese, |
| 40 | ASCII + JIS X 0201 + JIS X 0208-1978 + JIS X 0208-1983. |
| 41 | Some characters defined in JIS X 0208 are mapped to FULLWIDTH |
| 42 | area of UCS as specified in JIS X 0208:1997. |
| 43 | |
| 44 | This encoding is a "compatible" version of |
| 45 | C<iso-2022-jp> defined in Encode::ISO2022::SevenBit. |
| 46 | |
| 47 | When decoding, mapping tables from coded character |
| 48 | sets listed below to UCS are also loaded to restore |
| 49 | incorrectly labeled data. |
| 50 | |
| 51 | JIS X 0201 Katakana coded character set, |
| 52 | JIS X 0212-1990, JIS X 0213:2000 |
| 53 | |
| 54 | Note that for Windows user, Encode::ISO2022::CP932 |
| 55 | may be useful to try to restore broken "ISO-2022-JP" |
| 56 | data. |
