English ligatures are extremely far from what arabic needs. People
don't even actually know that there are ligatures in English, while for
arabic, people would even have a hard time reading something that isn't
using ligatures.

Err, I've very rarely seen the fi/ff ligatures on the console, it was
mostly from copy/pastes from pdf documents.

The console can do 512 glyphs, not only 256, so eastern europe support
is a matter of combining a latin1 font with parts of the other latin
fonts. That already covers a lot of european languages.
