Progress bars in QTerminal/Konsole

[tonsky]

This still happens on progress bars of some command-line programs. Can it be fixed in any way?

For example this is a progress bar that appears when loading a docker image with docker load:

Continuing with the conversation in #968, I tested the font in the suggested code editors and it works as expected:

In Sublime it works in the text editor as well as in the Terminus plugin.

In VSCode ligatures work in the editor but not in the terminal (although maybe I am missing some configuration option)

kitty works!

Patched st works too.

I am afraid I can't check more terminals in my setup easily.

Given the results I suspect the bug is maybe related to Qt?

but not in the [vscode] terminal (although maybe I am missing some configuration option)

Current terminal rendering system used (xterm.js) doesn't support ligatures - microsoft/vscode#34103.

Although this reminded me to check my bookmarked issues for this and ligatures may be back in the vscode terminal soon (ligature support got merged into xterm.js in May) 🎉

Cool! That means that the issue with terminals themselves (QTerminal/Konsole), not the font. Consider reporting the issue to them

I'll do, thank you!

Here are the issue reports in case anybody ends here:

• Konsole: https://bugs.kde.org/show_bug.cgi?id=422431
• QTerminal: Incorrectly rendered ligatures with Fira Code lxqt/qterminal#684

Hi again,

a new piece of information has been added by one of QTerminal developers here: lxqt/qterminal#684 (comment)

Both bugs appears to be related to Qt not classifying FiraCode as a monospace font. Maybe some metadata is missing in FiraCode?
