Or coding-system decoding should be applied to events from

As mentioned, read-event did not do obey keyboard-coding-system in
earlier Emacsen, so any affected package is more likely to be fixed than
broken by making a change that reverts to this previous behavior.

This event might be the result of processing several raw events
(e.g. via keyboard-coding-system, input-decode-map, ...).
