Created attachment 113140 [details] Okular fails to display some non-ascii characters in main view Okular doesn't display some non-ascii characters in main view, however they appear in print preview and text selection tool menu. I found some bugs regarding non-ascii characters not being displayed in annotations, but nothing relating to main view missing some which subsequently appear in print preview, and nothing about it missing some but successfully rendering others.

I can see the characters, and I suspect it's a font replacement issue, as the not all the fonts referenced by the document are embedded. What is the content of the File->Properties->Fonts tab?

Please try to remove the tex-gyre fonts (or configure fontconfig to not use them as primary choice for Helvetica & co).
Wow that seems to have done it! Care to inform me why they were breaking things? I don't know much about fonts in general, or how linux specifically handles them. Those fonts apparently come from the texlive-fontsrecommended package, should I lodge a bug with my distro about it? Could it still be considered an okular bug, that it chose that font rather than a different one? Or is that up to a different subsystem? Shouldn't fonts list which symbols they have inside?
It's not an Okular bug. See these previous bugs: https://bugs.kde.org/show_bug.cgi?id=379057 https://bugs.kde.org/show_bug.cgi?id=357822 https://bugs.kde.org/show_bug.cgi?id=335058 https://bugs.kde.org/show_bug.cgi?id=332595
