Emoji / Unicode are not rendered correctly, regardless of font (incorrect width)
Before opening this issue, I did find this related issue: gnome-terminal#152 (closed)
I initially reported this over here: https://askubuntu.com/questions/1351278/unicode-characters-do-not-have-correct-width-in-the-terminal?noredirect=1#comment2457261_1351278
And then reported here: https://gitlab.freedesktop.org/cairo/cairo/-/issues/573#note_1423619
Text copied here: -------------------------_
This doesn't happen with all unicode characters, but does happen with scissors:
neovim:
scissors overlap the next character in neovim
vscode:
uses a different character / emoji set, but it looks like vscode renders differently, as there is no overlap
gedit:
renders as I'd expect: no overlap
terminal:
has the same problem as in neovim
GitHub in Firefox looks correct
Is there a way to configure the terminal to have consistent emoji/unicode width/rendering?
One of the commenters, Raffa, pointed me at Cairo.
I'm using gnome-terminal.
