'Brill' is a serif font in the Baskerville tradition. My first impression is that its Latin and Greek characters look quite elegant (actually it looks quite like Gentium, which is the font Brill has previously recommended to authors). More importantly, it is a Unicode font with no fewer than 5,100 characters including a complete set of combining diacritics. So it should be possible to write just about anything with any accent in most major languages (though I do have certain reservations about the appearance of its Hebrew characters).
Only time will tell whether it will become a regular part of my editorial armoury, but it certainly looks like a useful addition to my list of fonts.
