Input Key Selection - Localisation

I have localisation and was wondering how it works with the InputKey Selector. All my localisations are fine except for this.

For example if I have the Use Key set to E it shows E and if I then change language to Chinese I can’t see it iand any other keys for the game in chinese (everything else translates just fine).

Is the reason because my keyboard is not setup for chinese, Japanese, korean etc therefore I wont see the equivalent for the E key as its based off the keyboard?

Does anybody know how this works?

Thanks.
