For this to really work, we need to add the missing font characters. @watabou is it possible for you to regenerate the font files adding at least the latin1 character set? That will cover a few dozen languages, at least.

If it's not possible / too time consuming, we can do some trick in-code to treat accented characters as non accented for now, or something similar.
