Same problem here. Appears randomly, only tab reopening fixes the issue.

Hi, i stuck again with same problem! I reopened tab and everything is fine.

I have the same issue. If I close this PS window and open it again it works fine.

I have same problem 😕 But I have this problem not only in Windows Terminal, but also in PowerShell itself. On the command line, everything works fine.

P.S. Found a fix. If you have the same problem as me, then updating PSReadLine to the latest preview version can help you. Check out this https://github.com/PowerShell/PowerShell/issues/10794 and this https://github.com/PowerShell/PSReadLine for more information.

Same issue on every windows PC which I have and had. You can’t copy-paste capital letters into PowerShell, they will be deleted. Also you can input capital letter only by using Caps Lock. Shift + key combination doesn’t work neither.

@schebotar As described in https://github.com/PowerShell/PowerShell/issues/10794, you need to update PsReadline. This will be present in all Terminal versions, because it’s a PsReadline bug.

You can find your current PsReadline version with

$(Get-Module PSReadLine).Version

I checked out all standard russian cyrillic layout. I can’t type capitals which I kept lowercase on screenshot below

Will capital letters be printed if you try using <kbd>tab</kbd> autocomplete?

Does setting "experimental.input.forceVT": true, in your settings fix this?

Can you type capital letters in other shells other than powershell?

Which powershell version? PSReadline version?
