It's a feature, but it has a bad effect in the above case.

C-u C-x = (describe-char) tries to display the character at position in
*Help* buffer as the same way as in the original buffer by
adding the same text properties.

      (setq item-list
            `(("character"
               ,(format "%s (%d, #o%o, #x%x)"
                        (apply 'propertize char-description
                               (text-properties-at pos))
                        char char char))

Changing that part to something like this:

      (setq item-list
            `(("character"
               ,(format "%s (displayed as %s) (%d, #o%o, #x%x)"
                        char-description
                        (apply 'propertize char-description
                               (text-properties-at pos))
                        char char char))

may be an improvement.
