First, JIS-X-0208 and JIS-X-0212 are not in IANA Charsets,
moreover those correct names as spec are JIS X 0208 and JIS X 0212.

Second, JIS_C6226-1983, JIS_X0212-1990, and EBCDICs are not
ASCII compatible. So they are out of discouraged; mustn't use.

Finally, Why ISO 2022 series is discouraged is not clear.

Anyway, most of charsets defined RFC 1345 are not clear.
Conversion table between Unicode is needed.
