Part of the recipe is that you don't set Arial Unicode MS as the default font, you let the font fallback find it (in the case of the original report, or MS Mincho in my case).

Although I still can't reproduce the problem

I wonder if the default font contains the character U+2203 in your case, since you are using a Japanese locale. Can you try reproducing it using the other characters suggested in the original message: U+2202 and U+FFFD?

In my case I only see the problem with U+2203 with emacs -Q, but I did originally reproduce the problem with one of those other characters after changing the default font to something else.

(let ((str (char-to-string (decode-char 'ucs #xFFFD))))
 (dotimes (i 16)
   (setq str (concat str str)))
 (insert str)
 (goto-char (point-min))
 (goto-char (point-max))
 (goto-char (point-min))
 (goto-char (point-max))
 (goto-char (point-min))
 (goto-char (point-max)))
