I have looked into my Linux box and found this in /usr/share/i18n/charmaps/BIG5.gz:
% Chinese charmap for BIG5 (CP950)

% This charmap is converted from:

There "my" characters are in.

That's a Microsoft's definition, not a standard. I think there should be a
reason why the Unicode org. does not use it.

Ok, I do not know the reason. But since also the glibc uses it, couldn't you use it too?
I believe the glibc delveloper have thought about this a lot. And they came to the
conclusion to use this definition. Why not postgresql?

Don't you agree that it is strange that I can (for EUC_TW) copy "to" file without error
but I can not copy "from" file without error?

I'm not quite sure what you are saying. Are you complaining that (for
example) 0xe7a281 in UTF-8 does not convert to EUC_TW?

Yes exactly, since this value comes from a "copy to" with PGCLIENTENCODING=EUC_TW

BTW, what do you think about below?

FYI, CNS 11643-1993 is the standard character set and EUC_TW is the
one of the encodings. That means your problem below will disappear.

Ok.

Hum. These seem to be CNS 11643-1993, plane 3. Currently PostgreSQL
supports only:

CNS 11643-1993, plane 0
CNS 11643-1993, plane 1
CNS 11643-1993, plane 2
CNS 11643-1993, plane 15

Would you like to have support for rest of CNS 11643-1993 planes:

CNS 11643-1993, plane 3
CNS 11643-1993, plane 4
CNS 11643-1993, plane 5
CNS 11643-1993, plane 6
CNS 11643-1993, plane 7

support for upcoming 7.4?
