Something that doesn't support cursor shapes
for example qterminal 0.7.1 or xfce4-terminal 0.6.3
The reproduce ways from neovim starting (Required!)
- Open neovim in a terminal that doesn't support cursor shapes
- Use Denite to switch buffers or files (example with
:Denite buffer) - Extra characters are displayed on the status line. In qterminal it is just a q. In xfce4-terminal it is a box containing "001B" a space and a q.
I am fairly confident this is caused by setting the guicursor option, which attempts to set the cursor shape with a control sequence, but ends up printing to the terminal if the terminal doesn't support the escape sequence. I suspect this was introduced by de58a9b.
