The reason why you can't input Hangul characters is that
your input method doesn't support it or it generates data
only in chiense-gbk encoding which can't contain Hangul
characters.

Provided that you have an input method that produces both
Chinese and Hangul and sends data to Emacs in compound-text
encoding, and you set keyboard-coding-system to
compound-text, Emacs should accept all characters, shouldn't
it?

Emacs is a multilingual editor and its functionality should
not be limited by locale.

In that case, Emacs asks you to select some of safe coding
systems.  If your Emacs supports chinese-gbk, it should also
be listed as a safe coding system.  I think that behaviour
is better than refusing characters not supported by
chinese-iso-8bit from the beginning.

Oops, then, I'm very sorry that I completely forgot about
that mail.  Could you send it to me again?  Then I'll check
why:

that happens.

By the way, the name non-standard-icccm-encodings-alist is
wrong.  "icccm" should actually be "ctext".  I'll fix it
soon.
