Introduction
I am using terminals like Wezterm and Xterm on Ubuntu to connect to Windows via SSH.
The default shell in this setup is WSL.
However, upon starting Vim, none of the operations involving the Ctrl key, such as Ctrl+W and Ctrl+R, work.
The keys Ctrl+C and Ctrl+Z function perfectly in the Bash shell, so this issue appears to occur only when Vim is launched.
Interestingly, this issue doesn't occur when using gnome-terminal.
Additionally, when using the Using terminals like wezterm and xterm to connect to an Ubuntu system via SSH, the problem does not occur.
Honestly, I'm not sure if this is an issue with Win32-OpenSSH that needs fixing, but I'm interested to know why this happens.
Expected behavior
Control key should work in Vim while using Wezterm or Xterm.
Actual behavior
Control key does not work in Vim while using Wezterm or Xterm.

Research direction
Start by reproducing the reported matrix: Vim over SSH from WezTerm and Xterm to WSL, then compare it with gnome-terminal and the Ubuntu target described in the issue. Check the behavior of Ctrl+W, Ctrl+R, Ctrl+C, and Ctrl+Z in each setup; done means identifying the terminal or SSH interaction responsible and documenting the expected behavior or a confirmed fix path.
