source-han-sans font release several days ago, it's opensource. Project homepage: https://github.com/adobe-fonts/source-han-sans/. 1. Open LibreOffice Writer and input some text, "This is a test", or Simplified Chinese "这是一个测试" 2. Export to PDF file Result, Libreoffice Writer close immediately, when I restart Writer, it would ask me to restore the file. I'm sure if it's LibreOffice's issue, but I think I should report this, and I will also open an issue on https://github.com/adobe-fonts/source-han-sans/ Operating System: openSUSE Version: 4.1.6.2 release
Here is the issue: https://github.com/adobe-fonts/source-han-sans/issues/27
