When trying to undo things (Ctrl + underscore) inside emacs -nw I get the delete behaviour (previous char is deleted).
shokey show also that the ket send is not C-_ but ^?:

 showkey -a

Press any keys - Ctrl-D will terminate this program

^?      127 0177 0x7f
^D        4 0004 0x04

Repro Steps

Run wsl with french keyboard layout
Start emacs -nw
go to scratch buffer (C-x b return)
write some text
move cursor in the middle of the text
hit C-_
the char before prompt is deleted instead of last written one

Expected Behavior

C-_ should correspond to undo

Actual Behavior

C-_ correspond to delete

Have seen another issue with indian layout that was adresses to windows terminal but that occurs with all terminal windows native I tested (microsoft/terminal#11194).
It does not happen with emacs graphical or ubuntu graphical terminal (terminator installed via apt-get)

Any news/comment on that ?

This issue is related to emacs configuration. WSL doesn't have control over emacs' behavior

[XL64]

No it's not. shokeys -a show the same issue with no link to emacs configuration and same emacs working correctly within native linux terminal or in graphic mode. All windows native terminal I tested are affected.

@OneBlue could you reopen this issue has I really think it is a WSL issue with french keyboard layout (try showkeys -a using french layout and hit C - _. Other people working with me can reproduce it also).

Sorry for that it seems to be a Terminal issue which was solved in 1.20 (microsoft/terminal#8458).
