Works fine for me, guess there's something wrong in [k]ubuntu.

If your distribution can run flatpaks, can you confirm that using https://flathub.org/apps/details/org.kde.okular works for you?
Comment 5 Egbert Gerber 2021-05-17 21:34:07 UTC 
This flatpak version is one of the two Okular versions I tested, it does not work.

The one from the Kubuntu backports PPA (http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu/pool/main/o/okular/okular_20.04.0-0ubuntu1~ubuntu20.04~ppa3_amd64.deb, says version 1.10.0 in the About dialog), does not work either.

i see you mentioned that originally, sorry.

That's indeed surprising.

Can you attach a screenshot of file->properties->fonts?

no problem :-)
Comment 9 Albert Astals Cid 2021-05-17 22:21:16 UTC 
Yeah, uninstall that tex-gyre stuff, or fix your fontconfig configuration to give /usr/share/fonts/gsfonts/NimbusSans-Regular.otf when asking for an "Helvetica" font.

Interesting, is that with flatpak still?

Yes, with Flatpak and deb versions, as before.

Ok, i'm out of ideas what may be wrong on your side that makes it not work :/

Well, same here... Thanks a lot for trying though!
Comment 16 Egbert Gerber 2021-05-22 16:33:42 UTC 
It seems the parts not rendered by Okular are not using Helvetica but the embedded subset of DejaVuSans/DejaVuSans-Bold
Comment 17 Egbert Gerber 2023-03-20 16:50:31 UTC 
Renders nicely in Okular version 22.12.3 (Kubuntu 22.10, Plasma 5.27.3, KDE Fraeworks 5.104.0, Qt 5.15.6, X11))
