It is common knowledge that when it comes to passwords et al. you should stay within the bounds of the ASCII character table - because - ASCII is the only charset which is guaranteed to produce the same result on different systems.
Yes - the location of the characters within a keyboard layout may deviate but - the keycode produced for an ASCII character will always be the same no matter the layout.
If you press A on the AZERTY layout it produces the same A on QWERTY.
This is the most important point that was overlooked in the previous thread. I don’t know where this miss-conception come from, but no, if you press a A on the AZERTY layout but the QWERTY layout is loaded, a Q will be produced, not a A. So, even if you use ASCII only character, you will still be impacted by this.
When you have used a keyboard for as long as I have - I learned typewriting in 1975 - the letters on the keyboard becomes irrelevant
I can see why this is not an issue to you, but this kind of “design choice” would throw off new users. Manjaro meant to be “user-friendly and suitable for those new to computers”.
A simple improvement would be at least an informative message inside the installer.
Yes, that would be the right thing to do in my opinion.
