Bug ID: 469455 Summary: Certain common math character not rendered Classification: Applications Product: okular Version: 23.04.0 Platform: Manjaro OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: PDF backend Assignee: okular-devel@kde.org Reporter: schwimmbe...@gmail.com Target Milestone: --- SUMMARY I'm reading a scientific paper and came across a strange gap. Using other pdf readers like the ones provided by firefox and chromium browsers, the symbol was rendered correctly. The symbol in question being ∈. For some reason, it doens't render, leaving a blank void. The text can be copied, however, which results in this: `he ∈` and sometimes this `den ∈`, it appears to be random. It's possible this issue may need to be escalated to whoever maintains the poppler backend, if that's where the issue lies. The file in question is freely available here: https://www.dbs.ifi.lmu.de/Publikationen/Papers/KDD-96.final.frame.pdf The problem appears a lot on page 3. STEPS TO REPRODUCE 1. Open the example pdf 2. Scroll to page 3 OBSERVED RESULT There is a blank void where the character should be. EXPECTED RESULT The character should be rendered correctly.
