It seems not that bad for the translation from Unicode to Japanese EUC
(or SJIS or Big5).
Because Japanese EUC(or SJIS) has only Japanese characters and Big5 has only Chinese characters(regarding to only CJK).
Right?
It would be virtually one-to-one or one-to-none when translating
from unicode to them mono-lingual encodings.
It, however, would not be that simple to translate from Unicdoe to
another multi-lingual encoding(like iso-2022 based Mule encoding?).
