Good old AZERTY vs QWERTY vs QWERTZ. No, the keyboard ROM remains the same.
Enhancing the IIe just requires a video ROM with mousetext replacing
the extra set of inverse capital letters (plus a 65C02 and new CD & EF ROMs).

I wondered what it looked like. I have only seen the UK version we got here
in Australia. Its keyboard ROM does nothing different based on the switch
as all that changes in the video ROM is the # becomes a UK pound sign and
both these have the same ASCII code. The 3 key has both symbols on it.

The US IIe has Dvorak layout in the other half of its keyboard ROM but no
easy way to access it (no switch under the keyboard). They fixed this with
the IIc by having a switch on both the NTSC and PAL models.
