strange <80><fc>^B characters after csw" surrounding

[mkreim]

Hi,

I have a problem with the surround plugin and I have no idea what is causing it or how to debug into it to find the source.

So what happens is:
I have a text like:

server

I place the cursor somewhere in the word and type csw"
and I end with (for a strange reason I cannot copy it therefore the screenshot)

• The problem occurs only in gvim and not in the terminal.
• I am running ubuntu 20.04 LTS
• and using a self compiled version of vim:

Do you have any ideas what this is causing it? Is this a strange utf-8 problem with the gui vim version?

Thanks a lot

I also experience this issue using neovim in the foot terminal on archlinux. Strangely, it isn't a problem in alacritty.

@MyBeansAreBaked are you seeing this with neovim before the 0.7 release?

Background: latest git version of foot does not have this issue. When I bisected it, the "fix" was related to neovim 0.7 improving their support for disambiguated keys. Thus, I expect older versions of neovim also does not have this issue (on foot).

@dnkl hanks for the info. Downgrading to neovim v0.6.1 does fix this issue in the stable foot release. Upgrading to the git version of foot (1.11.0-164-gdd03e10c) also fixes this issue, on neovim v0.7.0.

I suppose that this original ticket must have been to do with an issue in gvim.

[dnkl]

Fixed in foot-1.12.0

edit: not the original issue, though!

The original issue was about GVim on Ubuntu. I'm not seeing it on the new 22.04 LTS, so I'm going to chalk this up as another case of a fixed bug in other software, until I hear otherwise.
