PDF export breaks glyph. When using the font “EB Garamond 12”, the glyph for “m” is broken when using LibreOffice’s PDF export function. This bug is not specific to Writer, but also occures in Calc. When printing to a virtual PDF printer, than there is no problem.

Confirming the visual glitch in your LibreOffice export to PDF vs. your Ghostscript 9.14 based PDF24 virtual printer. As you are working on Windows with an 32-bit x86 build of 5.1.1.3, is OpenGL enabled or disabled? And on what release of Windows? Helpful if you copy and paste the details from the Help -> About LibreOffice panel. Also, as "EB Garamond 12" is not a common font on Windows builds, please embed in your sample ODT (File -> Properties: Font tab) and perhaps bracket the "m" with some other text to make it possible to locate more easily in the PDFs.

I’ve tried to embed the font as you described. But the resulting .odt file has 11 MB. (Despite that the font file itself has only about 500 kB.) As this exceeds the bugzilla size limit for attachments, I cannot upload the .odt file. Instead, I’ve uploaded the font file directly (only this special font of the font family). I hope this is okay; it is licensed under the SIL Open Font License 1.1. You can get the full package with all fonts of this font family from the author https://bitbucket.org/georgd/eb-garamond/downloads/EBGaramond-0.016.zip
Is the enormous file size increase with font embedding a separate bug?

That was exactly what was needed, but it appears OpenGL is not the issue here. Thanks for posting the EB Garamond 12 font--nice that it is SIL Open Font License Yes, I can reproduce on Windows 10 Pro 64-bit en-US with Version: 5.1.2.2 (x64) Build ID: d3bf12ecb743fc0d20e0be0c58ca359301eb705f CPU Threads: 8; OS Version: Windows 6.19; UI Render: default; Locale: en-US (en_US) STR 1. install linked EB Garamond 12 font 2. launch Writer (disable OpenGL rendering and restart if needed) 3. write a couple lines of sample text--I used font name and multiple "m"s, in the default Liberation Serif 4. copy lines, paste 5. change font for pasted selection to EB Garamond 12 6. save to .ODT 7. menu -> Export as PDF 8. in PDF dialog select lossless compression for images, and PDF/A-1a (ISO 19005-1) in general tab 9. export 10. open the resulting PDF in Adobe Acrobat Reader -- zoom resolution > 400% Visual glitch in forming the right leg of the "m" as in attachment 124121 [details] Various "print" to PDF methods (Adobe, MS, gs) do not exhibit same issue--so believe issue is in LibreOffice's PDF composition. Rendering glitch of the font on export to PDF is also present from Draw text box.
