I reported this issue to LibreOffice upstream and further tracked it down. https://bugs.documentfoundation.org/show_bug.cgi?id=105159
As it turned out, I could solve it by installing a font-package and clearing the font cache (documented in my upstream bug report). As it turned out, this is not an issue at all. Not in LibreOffice and not in ubuntu. The only thing is that it happened after upgrading from 14.04 to 16.04. So maybe the update process could be slightly improved. At least a fresh install of ubuntu 16.04 behaves correct out-of-the-box. ** Bug watch added: Document Foundation Bugzilla #105159 https://bugs.documentfoundation.org/show_bug.cgi?id=105159 ** Changed in: xfonts-base (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xfonts-base in Ubuntu. https://bugs.launchpad.net/bugs/1604182 Title: Some Arial characters have serifes in 16.04 Status in xfonts-base package in Ubuntu: Invalid Bug description: Some of Arial's special characters are rendered with serifes in 16.04, as shown in this image attached In 14.04, the characters in the circles did not have serifes and were rendered like normal Arial characters (with a circle around). I also attached an image which was rendered with Arial in 14.04, looking much more like Arial. At any time, I had package ttf-mscorefonts-installer installed.
