No problem for Hangul, which is a completely different script.
But for most Hanja (ideographs as used in Korea) and many Kanji
(only many because some are already the same as SC, and in
some cases, Japan has it's own simplifications), there is
absolutely no chance to be successful (i.e. only map SC/TC,
but not Hanja or Kanji). If that's the requirement (and I
agree it is), then we don't have to continue the discussion.
Sorry if I disappoint anybody :-(.
