Support for non-latin languages

[Suhail Alkowaileet]

I think is supporting other languages is important.

I've tried to do that and what get when I'm writing in Arabic for example 'سلام' I get '????'. This is because the font doesn't include these charters. I've changed the font builder to add Arabic and it worked for some fonts "sans probably" . so my suggestion while the sans is the default font, we make it for all the sizes 'sans-9, sans-10, sans-12...etc' then when the unifont didn't find it. it finds in the sans version, if it was not found then we print ?.
