Broken input in fish shell

[sboukortt]

Windows Terminal version

1.25.622.0

Windows build number

10.0.26200.0

Other Software

fish 4.5.0 in msys2
bépo keyboard layout: https://cdn.bepo.fr/windows%2Fbepo.exe

Steps to reproduce

Use any of the following key combinations:

• AltGr + y (the key labelled x on a QWERTY keyboard)
• AltGr + x (the key labelled c on a QWERTY keyboard)
• AltGr + ( (4 in QWERTY)
• AltGr + ) (5 in QWERTY)
• AltGr + k (b in QWERTY)
• AltGr + Space

Expected Behavior

• AltGr + y produces {
• AltGr + x produces }
• AltGr + ( produces [
• AltGr + ) produces ]
• AltGr + k produces ~
• AltGr + Space produces _

Actual Behavior

In Terminal 1.23.20211.0: the characters appear as expected.
In Terminal Preview 1.25.622.0: they don’t. This is a regression. (AltGr + k, in addition to not producing ~, also seems to trigger some action in fish.)

My suspicion, without having looked that much into it, is that AltGr might now be treated more like Alt than it should.

Thanks for filing! Can you turn off "Allow Kitty Keyboard Protocol" and let us know if that fixes the issue /?

[sboukortt]

Thank you for the suggestion. Unfortunately, that doesn’t seem to solve the issue.

Excellent! That means it's in the new input stack rather than specifically the kitty part of the new input stack.

Bepo crashes Explorer on the latest Windows 11 version and prevents activating the layout. Brilliant. lol
