I have Ubuntu 11.04. Yesterday I installed VirtualBox and the encoding was wrong (I couldn't read anything). I know its UI very well so I tried changing the UI display language but it didn't work as all the languages had the same issue. I also noticed that libreOffice had exactly the same problem so I decided to look deeper into it. I found that:
- Both VirtualBox and LibreOffice depend on Qt libs like libqtcore4. And Qt is used by KDE apps. But other Qt based apps like Okular are functional.
- In previous installations, I remember that VirtualBox and LibreOffice were using Greek by default. My attempts to change the language to English failed as well.
- I experimented with locale, update-locale and their ENV variables (LC_ALL, LANG and LANGUAGE) but it had no effect.
I'm out of ideas and I haven't been able to find a decent solution. I'd really appreciate tips, hints or suggestions.
