Ubuntu 22.04 non-latin layout not work with ctrl+shift kitty_mod

[thedrint]

Describe the bug When i press Ctrl+Shift+Й (it's C-s-q in russian layout) - Kitty doesn't close tab, but sends sequence of symbols.

To Reproduce Steps to reproduce the behavior:

1. Run simple test kitty --debug-input --config /dev/null
2. Press Ctrl+Shift+q in opened kitty window -- it would closes
3. Re-run test but with non-latin layout enabled (russian for example)
4. Press same combination (Ctrl-Shift-q) in non-latin layout - kitty wouldn't closes but sends in terminal something like 81;6u

Screenshots English layout while run test

Additional context I've using CAPSLOCK as layout switcher.

Well, yes, you are not pressing ctrl+shift+q you are pressing ctrl+shift+Й

If you want this key press to quit kitty add the appropriate mapping to kitty.conf

map ctrl+shift+Й whatever

kitty only matches shortcuts based on what the key means in the current keyboard layout.

[thedrint]

map kitty_mod+q close_tab
map kitty_mod+й close_tab

Thank you for advice, it really works when i duplicate in kitty conf mappings with non-latin letters:

Is there any hack/rule/option/setting to avoid kitty receive those long sequences like 81;6u when pressing combo with non-latin keys? Or I must to add all possible map variants to kitty.conf with no_op?

[kovidgoyal]

No I'm afraid there is no hack for it. You would need to map any problematic key preses to no-op in kitty.conf individually.

[Jakeroid]

Here is mine solution. Actually, the idea is the same to map each shortcut for the non-Latin character, but I made automated script to do that.
