Yes. It looks very good to me, too.

I ran the following test.
First, I applied a old patch.
I saved a file with VIM with the option "set fenc=cp949".
Then I loaded the file with EMACS. It is broken in my UTF-8 environment.
So I was typing "M-x revert-buffer-with-coding-system", "cp949", then
it looks well.

After applying this patch, I ran a same test.
It shows a wrong letter.

I guess the problem is related to coding system.

The problem that "HANGUL SYLLABLE HAEH" is shown "HANGUL SYLLABLE
JWIG" occured in EUC-KR coding system.
Because "HANGUL SYLLABLE HAEH" is not contained in EUC-KR region.
But CP949 contains "HANGUL SYLLABLE HAEH".
This patch could not fix it.
