borg2 --cockpit looks bad with some terminal types

[ThomasWaldmann]

I was using my macOS machine to ssh into a linux server, running borg 2.0.0b20 in a screen session there:

borg --cockpit create --repo REPO --list ARCHIVE ...

It looks quite bad:

• it outputs a lot of "?" instead of the graphical block and lines chars.
• also the layout seems to be disturbed
• after quitting borg cockpit, the terminal needs a reset to be usable again

Maybe an issue in textual with terminal type detection or support?

Or the terminal just can't support what's needed by textual / borg?

In a tmux session, it looks a bit better, but also not 100% correct.

For comparison: this is using a plain ssh session on the same machine, without tmux or screen:
