Itʼs anything that goes through `key-translation-map'. How
about:

    *** 'C-h k' ('describe-key') shows Unicode name.
    For keybindings which produce single characters via translation (such as
    those using the 'C-x 8' prefix), 'C-h k' now shows the Unicode name of
    the produced character in addition to the character itself, e.g.

    'C-h k C-x 8 E' =>

        € 'EURO SIGN' (translated from C-x 8 E)

    *** 'C-h b' ('describe-bindings') shows Unicode names.
    For keybindings which produce single characters via translation, the
    Unicode names will now be shown in addition to the character itself,
    i.e.

        A-!			¡	INVERTED EXCLAMATION MARK
        A-$			¤	CURRENCY SIGN

    and so on.
