Sorry, I do not know anything about conversion maps and CNS 11643-1993 planes.
I only got a file in BIG5 encoding from Taiwan and found that it is not possible
to load all text to postgresql 7.3.3.
But it is possible to convert to UTF-8 with iconv tool from glibc (Linux).
It would be good if next release supports todays BIG5.
