I decided to try it again on my computer since it was a while since this bug was originally filed.
I went back in and ticked "use system font for user interface" and then restarted LibreOffice and guess what - it worked! So I presume an update, either to Ubuntu or to LibreOffice has corrected the problem. I'm now using Ubuntu 12.04 whereas this bug was reported in Ubuntu 11.10 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/908465 Title: Hebrew Menus texts unreadable - characters show up as square blocks Status in “libreoffice” package in Ubuntu: New Bug description: I have my system locale set to Hebrew. Most applications seem to work fine, but recently I have noticed that LibreOffice has become unusable because the menu texts all show up as square blocks. Other applications display Hebrew in their menus fine so it is somethin specific to LibreOffice. WORKAROUND: Set the Locale to English (or another language that the Ubuntu font displays correctly), from within LibreOffice go to Tools -> Options, View and untick 'Use System Font'. Then set the locale back to Hebrew and all displays correctly, albeit in a different font.
