I guess I used the old mm-util.el mistakenly.  It doesn't use
the `unicode-precedence-list' function that adds the utf-8
charset set containing `jit-ucs-charset-0'.  But now it's been
solved:

(split-char ?❤)
 => (jit-ucs-charset-0 32 33)

(require 'mm-util)

(assq 'utf-8 mm-mime-mule-charset-alist)
 => (utf-8 ... jit-ucs-charset-0)

(with-temp-buffer
  (insert "I ❤ Unicode")
  (mm-find-mime-charset-region (point-min) (point-max)))
 => (utf-8)

However, I wonder why your Gnus v5.10.6 encodes it correctly.
Because the date that I added `unicode-precedence-list' to
`mm-mime-mule-charset-alist' was 2006-06-06 and it should be
neither in Gnus v5.10.6 nor the Gnus XEmacs package. ;-)

Thank you very much for fixing the bug:

I've verified it solves the problem.
