Test case described in bug report
Hi, thank you for the report! The fix will be in the next update - ghostscript-9.50-1 The issue is quite tricky one - loading fonts from /usr/share/fonts actually works. I created test which installs needed fonts and it passes during testing for old gs version, but, curious enough, there are messages about missing fonts when I run it manually. Output of test: Querying operating system for font files... Can't find (or can't open) font file /usr/share/ghostscript/Resource/Font/SourceCodePro-Bold.

Can't find (or can't open) font file SourceSansPro-SemiboldIt. Didn't find this font on the system! Substituting font Helvetica-BoldOblique for SourceSansPro-SemiboldIt. Some fonts were not loaded now, why? Then I saw the message: .... Can't find (or can't open) font file /usr/share/ghostscript/Resource/Font/SourceCodePro-Semibold. Can't find (or can't open) font file SourceCodePro-Semibold. Loading SourceCodePro-Semibold font from /usr/share/fonts/adobe-source-code-pro/SourceCodePro-Semibold.otf... 4373016 2751713 3977728 2658006 1 done. .... What? Successful load from /usr/share/fonts? It seems the problem is not about gs is not able to read fonts from /usr/share/fonts, but it is rather connected to the issue I found yesterday: When fontconfig returns error for one of existing fonts, gs does not continue in loading other fonts. So the issue is rooted in the font/fontconfig, but improper error handling in gs causes no loading of other fonts found by fontconfig. But I'm not sure why fontfonfig returns different value during testing than ran manually. Silly mistake - difference between running in test and running it manually is that font which I put into /usr/share/fonts is cleaned up... In the end, the fix can be backported. Moving to F31, the update will be in the stable repo faster, so the bug will be closed faster. The fix will be for F30 too, but I'm not sure how fast will it be (depends on the number of willing tester on F30). FEDORA-2020-5ba7efcc1c has been submitted as an update to Fedora 31. https://bodhi.fedoraproject.org/updates/FEDORA-2020-5ba7efcc1c ghostscript-9.27-3.fc31 has been pushed to the Fedora 31 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2020-5ba7efcc1c The fix may works as a workaround but it looks like the fixed code stops supporting (a part of) variable fonts. (In reply to Akira TAGOH from comment #9) > The fix may works as a workaround but it looks like the fixed code stops > supporting (a part of) variable fonts. To be precise - it does not stop support of variable fonts since it seems there was no support of them to begin with. As I wrote in #1813187, would you mind helping me how it should be taken care of properly? I don't have much experience in fonts. Or, if you are willing, join me at #ghostscript at irc.freenode.net and talk with upstream about it? I added a comment there. and yes, that's true. that's why I wrote it as "a part of". in fact, currently only named-instances are supported. I can't say more details how to do it because I don't know how ghostscript use those values from FcPattern and render. They may also need to use the proper API from freetype to support variable fonts. see around this https://www.freetype.org/freetype2/docs/reference/ft2-multiple_masters.html#ft_mm_var ghostscript-9.27-3.fc31 has been pushed to the Fedora 31 stable repository.
