S-exps in the form of ?\N{char_name} return wrong values for some
characters.
The S-exp below inserts a whole list of such characters.

(dotimes (u (1+ (max-char 'ucs)))
  (let* ((name (get-char-code-property u 'name)))
    (when (and name (not (<= #xD800 u #xDFFF)))
      (let ((u2 (condition-case err
                    (read (format "?\\N{%s}" name))
                  (error 0))))
        (unless (eq u u2)
          (insert (format "%X\t%s\t%X\t%s\n" u name u2
                          (if (= 0 u2)
                              "error"
                            (get-char-code-property u2 'name)))))))))
