I assume it will never do due to unification rules. So one more reason to
use ISO 2022 if you need linguistically exact information on CJK
characters. Of course, it's possible to use SGML tags or something like
that to select the proper variant of the unified Unicode character, but
this is neither elegant nor readable.

Another interesting approach is Christian Wittern's Chinese Encoding
Framwork (CEF) (see for details): he uses SGML
entities to indicate an embedded character from another encoding (e.g. in
Big 5 text, the entry &C3-265F; indicates the character 265F from CNS
plane 3).
