I was wondering what fonts are used in Ubuntu 11.10 and are they open source? The fonts used in Ubuntu have very cute Armenian character support, that's why I would like to know them, so I can install them on my Symbian smartphone whose fonts do not have Armenian character supprt.

EDIT: I would love to get additional information. In Firefox web browser the Armenian characters are displayed properly, and I would to know exactly which one of the fonts is the one used in Firefox as there are a lot of fonts in the downloaded archive. –
