One of the basic things we’ve got to choose is the font we’ll be using. We need a sans serif font, with many weights and good quality. I personally like the new humanist sans fonts that have appeared (and almost dominated) the digital type in the last few years. Very nice examples are the Nokia Pure font, the Segoe UI font and Ubuntu.
For a free project we obviously need a free font. There is a very nice free/open source font recently developed by adobe, Source Sans.
That would be my choice for the nemo main font but, it doesn’t yet speak Greek, and you know, I would be filing bugs about my own choice
I’d like to note here that Greek and Cyrillic are a bit different than all the other scripts out there that can easily use their own font. Because Greek and Cyrillic have common glyphs with Latin, it’s important that they look the same. Especially for Greek as the GSM alphabet is mixed Greek/Latin (there is no true Greek support but only the capital Greek letters that do not have counterparts in the latin alphabet exist). Thus, if we had to fall back to another font, different fonts would be used only for the missing glyphs and Greek SMS message would look like this:
ΣΑΣ ΛΕΩ KAΛΗΣΠΕΡΑ
unacceptable and unprofessional
It’s a font that looks modern, it’s easy to read, has many weights and isn’t extreme in any way. The only thing I have against it, is that it’s being used too much.
