Hebrew displays squares under Ubuntu

[ilan]

If you are not aware of this, Hebrew doesn't display correctly in Ubuntu 11.10. It seems to be missing a font but I don't know what the font is.
Sorry, I forgot to mention that this is teamviewer 7, both the 32 and 64 bit versions. Specifically the teamviewer dialog boxes display square characters where the should be displaying Hebrew characters.

Thanks,
Ilan
