I don't know exactly what kind of encodings you wish to use, but I
think MULE_INTERNAL might help you. It's actually mixture of various
encodings with encoding-prefix added to each letter.  For example if
you can mix KS5601 (Korean) and Japanese Kanji (JIS X0208) in a *same*
column. So if you don't have problem with sorting KS5601/JIS X0208
with C locale, you should not have problem with MULE_INTERNAL too in
theory.

Remaining problem is how to display the Korean-Japanese mixed string
in your client, but this is not PostgreSQL's problem, of
course. However you could write your own conversion function
MULE_INTERNAL <--> UTF-8, and might be able to solve the problem.
