Usually, yes.  But as far as there is a code space in high
area for a CJK charset, it is unavoidable to have a
buffer/string that contains a character represented by a
byte sequence in that high area as the test case of
Bug#11073.  And, as "unification" means to treat such a
character the same way as the unified character, I thought
they both have the same character code.
