I'm loving Lubuntu so far, but I have been noticing certain problem with some applications, mainly VirtualBox.
Basically, even though my system is set in English (US) with regional settings in Spanish (AR), when I open VirtualBox it displays all the UI in Greek characters. Not in Greek, though -- it just displays the English text but using Greek characters. I have tried switching VirtualBox's language to Spanish and relaunching the program, and the same happens -- it displays the Spanish text but using Greek.
Here you can see what I mean:
It also happened with other applications downloaded from the Lubuntu Software Center, such as Wine Launcher Creator. I guess it's an encoding problem? I tried googling it but all the answers I find deal with language settings, which clearly isn't the problem here, since the program is in fact displayed in the language I want -- it's the way the characters are displayed that isn't right.
