I agree on this point.

ISO 2022 is available online as ECMA35 at http://www.ecma.ch so that you
can take a look at it yourself. ISO-2022-JP and EUC-JP are two different
character set encoding schemes for coded character sets JIS X 201(and/or
ISO 646/US-ASCII), JIS X 208 and JIS X 212. Likewise, EUC-KR and
ISO-2022-KR are two different character set encoding schemes for coded
character sets KS X 1003(or ISO-646/US-ASCII) and KS X 1001. All four
of character (set) encoding (schemes) are compliant to ISO-2022. In
addition, IETF RFC 2130 and RFC 2278 are worth looking at. At least in
MIME context, character set (coded character set) and character (set)
encoding (scheme) should never be mixed up with each other as was done
by some employees of MS (Korea). Ken Lunde's 'CJKV Information
Processing' is another good reference in this regard.
