  • Your Windows build number: My build is : Microsoft Windows [version 10.0.18362.1]
    Using vscode 1.32.3 with conpty enabled.

  • What you're doing and what's happening:
    When trying to type some specific character with a french keyboard layout, an extra character ("é") is added. For now I spotted 2 characters, ~ and . More precisely, if I press "alt gr" and 2 at the same time, a "é" is added. If I then press space, then I have "é~" in the prompt. If I press "alt gr" and seven at the same time, a "é" is added. If I then press space, then I have "é" in the prompt.

  • What's wrong / what should be happening instead:
    What should happen is that no ~ is added.

Note that it doesn't happen if I disable conpty.
I didn't find a similar issue (it's not a newline)

I've filed MSFT:20921862 internally to make sure this gets investigated.

I don't know where the issue is in the stack, but just in case, it's still present with Terminal app (master, checked yesterday).

Using Danish keyboard results in invisible character being inserted when using alt gr to compose letters.

# cmd.exe
C:\Users\hilma\git>ver
Microsoft Windows [Version 10.0.18922.1000]
C:\Users\hilma\git>¨~ 

# wsl
$ cd ~
-bash: cd: $'\250~': No such file or directory

In practice I've had to switch to other terminals to use | (pipes) and vim, as it exists insert mode whenever I compose with alt gr.

Yes, this was fixed by #4192. Verified in VSCode, Putty, and Terminal. VSCode now produces qq for AltGr-2 Q, but no other terminal emulators using the same infrastructure do so. Any further bugs here are liable to be upstream's fault.

FWIW: I can't even reproduce this with the original inbox console host. Perhaps this was always VS Code's fault.
