Note that although other JISes such as JIS X 0212 and JIS X 9010 |
| 393 |
define ISO/IEC 2022-comfprming coded character sets, |
| 394 |
these standards do not define complete coding system (but define |
| 395 |
as used on ISO/IEC 2022 environment), so this module |
| 396 |
does not include those coded character sets. (IETF RFC 1345 |
| 397 |
and IANAREG give charset name to coded character sets |
| 398 |
consist of such standards. But those are defined by RFC 1345, |
| 399 |
not by JIS. Such coded character sets should be implemented |
| 400 |
in Encode::ISO2022::RFC1345.) |
