Typing 'M-x list-charset-chars RET chinese-cns11643-15 RET',
a wrong character set is listed.
It contains hangul characters, and looks like korean-ksc5601 charset.

Why do you think this is an error?  CNS11643 has 16 planes and can
contain up to 141376 characters.  What is your reference for judging
which characters belong and don't belong to this character set?  Emacs
uses the glibc mapping.

Reading emacs-28.1/share/emacs/28.1/etc/charsets/CNS-F.map,
there are only UCS values for CJK IDEOGRAPH characters.
The result buffer of #'list-charset-chars contains non-han characters.
For example, '*Character List*' buffer starts with:
	Characters in the coded character set chinese-cns11643-15.

Thanks, should be fixed now on the emacs-29 branch.
