System lang switching breaks Godot Input

[olehpatrushev]

Godot version

3.3.stable

System information

Ubuntu 20.04

Issue description

According to the title, when I change system lang to some others from English (in my case Russian) on Ubuntu, I find that Godot shortcuts won't working in editor (even Ctrl+V), and runtime Input system also brakes (even W not working).

Steps to reproduce

Change system language to some other (maybe cyrillic on Ubuntu) and try to manipulate with Godot.

Minimal reproduction project

No response

Can you reproduce this if you exit and restart Godot with the keyboard layout in question?

Godot does not use physical input keys, which means you need to press the key for your current keyboard layout for shortcuts to work. Optional physical keys were added to #18020, but they're not used anywhere in the editor yet.

Yes. It is reproduced.

@olehpatrushev After switching keyboard layouts, do you press V as it appears on your original Russian keyboard layout, or V as it appears on a QWERTY layout?

[olehpatrushev]

@Calinou yes I do the same steps (shortcuts) as in other programs, such as Google Chrome, and it doesn't work in Godot, but in Google Chrome works.

You didn't answer the question - do you press the V key on the keyboard, or some other key?

[olehpatrushev]

@Zireael07 there is no V on russian keyboard layout

[Zireael07]

Do you press the key on the keyboard that is where a V would be in QWERTY, or what? Because if there's no V in Russian layout, that begs the question of how do Ctrl+V work in other apps?

[olehpatrushev]

@Zireael07 feel free to type any characters on keyboard in non-English layout, they would not work in Godot, I assure you.

AFAIK this is not a bug, just the normal behavior with scancodes. When the keyboard layout is remapped, the scancodes sent by specific physical keys are also remapped. Since there's no "V" key on a Russian keyboard layout, Ctrl+V can't match.

This could be solved in 3.4 with the new support for physical scancodes, which allow mapping keys to their physical position on a theoretical QWERTY keyboard layout, ignoring the user keyboard mapping.
