vim-surround at this commit, I think: https://github.com/tpope/vim-surround/tree/baf89ad26488f6a7665d51b986f5c7ad2d22b30b

Steps to reproduce

1. set keyboard layout to non-ANSI QWERTY (I'm using Canadian French, e.g. setxkbmap -layout ca)
2. enter neovim
3. enter insert mode and type 'a'
4. leave insert mode, put the cursor over the a, and type cs'" to change the surrounding ' to "

Expected Behavior

buffer contains "a"

Actual Behavior

buffer contains <80><fc>^B"a<80><fc>^B"

Additional notes

See also:

• strange <80><fc>^B characters after csw" surrounding tpope/vim-surround#313
• https://codeberg.org/dnkl/foot/pulls/1017

I believe this is caused by CSI u mode not having the semantics neovim expects. Following the semantics foot uses in the above PR will probably fix this. On my layout, " is Shift + 2 (and ' is Shift + ,, so this can be reproduced with other combinations of characters like cs"')

Merry christmas, @classabbyamp . I have fixed this now and it works for me (i could repro it using German keyboard layout as well). I would still like you to confirm that it also works for YOU. :)

You may need to rebuild from source. Please ping us, if you need some kind of assistance.

can confirm that it is fixed with that patch, thanks!
