Gentium has now been re-released under a license that permits modification and redistribution – the SIL Open Font License. This is an exciting new development that will give great freedom to people who find Gentium useful, and the freedom to extend the font if needed.
Update: a reader emails to say that the Greek Font Society has released an interesting font, GFS Didot, with the following statement regarding licensing: “You may use these fonts for personal and commercial use. These fonts may be freely redistributed, provided that you do not alter them in any way and that you credit GFS for this.”
