Bug 1753020

As a workaround removing all the fonts from /usr/share/fonts/terminus/ apart from ter-x*.pcf.gz fixes it. Is there a way of prioritising the ISO10646-1 font over the other code pages again?

Could you please attach a screenshot of what this is supposed to look like?

Being unfamiliar with powerline, I have no idea what your expected behaviour looks like.

Screenshot of expected outcome

This is a screenshot of the expected outcome. It is what happens when I remove everything but ter-x*.pcf.gz. It is also how it looked in the previous version of this font package.

My best guess is the upstream build process changed which characters are in which code pages, or something changed the order the code pages are loaded in.

I forget to mention, the reason for the misalignment in the first place is that it that for some reason it is loading up the terminus font without the powerline characters in it (Terminus does have support for these characters) so the font rendering system is falling back to the powerline TTF font for these characters. That fallback doesn't align well and didn't happen previously.

I cannot reproduce this on Fedora 31 with `terminus-fonts-4.48-2.fc31.noarch` installed. Neither in konsole nor in gnome-terminal.

Can you?

After all the stuff from bug 1748495 I suspect this also might have been fixed.

I couldn't reproduce yet with F30-WORK-x86_64-LIVE-latest.iso.

You will probably need to give more exact reproduction details: maybe related to ohmyzsh?

terminus-fonts-4.48-2.fc31.noarch still broken for me in Konsole (I don't have gnome-terminal). Not related to ohmyzsh, it happens in bash too when powerline characters are used.

If no one else can reproduce it and it affects no one else I guess it may be related to the Ryzen GPU and rendering or something, no one else seems to have those. Either way I'll just continue use a custom install of the font as a workaround for now.

Feel free to close as can't reproduce.

I tried Fedora-KDE-Live-x86_64-31-1.9.iso too in QEMU and didn't see it there.
I will try F31-KDE-x86_64-LIVE-20191206.iso later too.

Now I know why I did not see this bug any earlier:

It had mistakenly been filed against the long retired "terminus-font" package,
while the Terminus font has been packaged in the `terminus-fonts` package for
about 10 years.

I still need to verify this one.

I have just tried this on F34 and cannot reproduce any powerline
symbol alignment issues when running the following powerline test:

    [user@host ~]$ zsh
    [user@host ~]$ powerline-daemon -q
    [user@host ~]$ . /usr/share/powerline/zsh/powerline.zsh
     ~  
     user  cd ......../ndim-utils/_build/master 
     …/ndim-utils/_build/master   master  
     user  

For reference, the following packages were being used here:

    gnome-terminal-3.38.1-3.fc34.x86_64
    powerline-2.8-4.fc34.x86_64
    powerline-fonts-2.8-4.fc34.noarch
    terminus-fonts-4.49.1-12.fc34.noarch
    zsh-5.8-4.fc34.x86_64

Fedora 33 changed to end-of-life (EOL) status on 2021-11-30. Fedora 33 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
