Typo on my part. I meant 5, the combination of RIGHT_ALT_PRESSED and
RIGHT_CTRL_PRESSED. But RIGHT/LEFT CTRL should be equivalent anyway,
as far as general typing is concerned.

Yes, just like the german one. However, to the best of my knowledge
there's no printable unicode char which requires to press left-alt on
any such keyboard layout. That's exactly what the AltGr == right-alt
key is for, isn't it?

Uh, ok, I see. If you press AltGr on a keyboard layout which does not
distinguish Alt and AltGr, (english, for instance), the AltGr key only
emits a RIGHT_ALT_PRESSED control code. On a keyboard layout which does
distinguish them, the AltGr key emits LEFT_CTRL_PRESSED | RIGHT_ALT_PRESSED.
So you need some CTRL_PRESSED to emit the correct INPUT_RECORD.
