Taking another look at the attached Postscript file, I found a small
glitch I overlooked before. The parentheses following EUC-KR has only
one of two character sets convered by the encoding, KS C 5601-1992,
leaving out KS C 5636-1993/US-ASCII while those following EUC-JP contain
all three character sets covered by that encoding, JIS X 0201,JIS X
0208, and JIS X 0212. As you know well, EUC-KR(encoding) is not
equivalent to KS C 5601-1992(character set) and I'm concerned this
diagram gives the false impression that they're equivalent. The same is
true of EUC-CN and EUC-TW. EUC-CN is not equivalent to GB 2312-80 but an
EUC encoding of US-ASCII/GB 1988-80 and GB 2312-80. By the same token,
EUC-TW covers not only CNS 11643-1992 but also US-ASCII.
Considering the confusion among many people about the
distinction(between encoding and character set/character repertoire or
in terms of RFC 2130, CES and CCS), I guess it's important to make this
point as clear as possible to avoid perpetuation of this unfortunate
mix-up.
