Braille symbols cause visual artefacts

[serpent7776]

Expected Behavior

Braille symbols don't break layout of TUI apps.

Current Behavior

Braille symbols cause visual artefacts, e.g. in btop and bottom.
The issue disappears if braille symbols are disabled.

Possible Solution

Braille symbols rendering is probably buggy and should be fixed.

Steps to Reproduce (for bugs)

1. Launch btop ar btm with braille symbols enabled.

Context

This breaks TUI layouts.

The same issue as #685. I have no idea how this can be properly fixed, though.

this seems to be #710 (comment)

or maybe not...

Thanks, I confirm that checking Preferences -> Appearance -> Use box drawing characters contained in the font helps with drawing the boxes, but I still see artefacts, e.g.

I'm now at QTerminal 2, Qt version 6.7.1.

excellent! I see that you're now affected by #1143
just like I am:

that patch fixed it for me
