[BUG] org-edit-special is not working with korean characters [9.6.6 (release_9.6.6 @ /home/sukbeom/opt/share/emacs/29.1/lisp/org/)]

Hi,

I found that there is a bug with typing Korean characters with table.el
table.

At first, I thought this was related to the Emacs's overwrite-mode issue
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66970), but it still not
be resolved even after applying the workaround patch.

The thing is, whenever I type korean characters within the table.el
table, it just inserts characters, breaking the table.

+----------+----------+-------+
|First row |Japanese  |Korean |
+----------+----------+-------+
|Test #1   |あえいおう|아에   |     <- expected
+----------+----------+-------+
|Test #1   |あえいおう|아에       | <- actual behavior
+----------+----------+-------+

The test sequence is,

1. Create a table.

| First row | Japanese | Korean |
| Test #1   |          |        |
| Test #2   |          |        |

2. Convert the table to table.el table. (C-c ~)
+-----------+----------+---------+
| First row | Japanese |  Korean |
+-----------+----------+---------+
| Test #1   |          |         |
+-----------+----------+---------+
| Test #2   |          |         |
+-----------+----------+---------+

3. Try to type characters
- <M-x> set-input-method
 -> japanese-hiragana
  -> aeiou => あえいおう
 -> korean-hangul
  -> dkdp => 아에

I use 'D2Coding' font to prevent Emacs from printing characters
unaligned between alphabets and CJK characters. And I found that this
issue is only reproduced within Korean characters, not other
Japanese/Chinese characters.
