From Victor Gualtney, on the latest regarding the Gentium font by way of the Gentium-Announce List (links mine):
Update #4 – Gentium project revived, Cyrillic, Charis
Dear friends of Gentium,
No – there’s not a new version out yet. 🙂 But we’re pleased to report that Gentium is under development again after a while in hibernation. We’re actively refining the Cyrillic, adding support for Unicode 5, and preparing the font for the addition of smart rendering support using three different smart font technologies – OpenType, Graphite and Apple AAT.
If you want to see the target character, glyph set and behavior we’ll be supporting in the next version, you can take a look at our Doulos SIL and Charis SIL fonts:
Gentium will support every character and behavior that these fonts do, plus Greek. This also means that if you’re wondering whether the next version will support a specific character, see if it’s in Doulos SIL or Charis SIL. Note that since these fonts do not support full Greek, some of the Greek improvements (digamma, etc.) will not be there, but will be in Gentium.
Because we want to get this major upgrade to you as soon as possible, the next version will still be only regular and italic. We hope, however to get it to you sometime mid-year (that’s 2007, if we’re able to keep on track).
One more little note: Since Gentium has been released under the SIL Open Font License, it has gained lots of support in the GNU/Linux community. It has also made its way into some Linux distributions, and even has been shown on the OLPC (One Laptop Per Child). There’s a good pic (in both large and small resolutions) of Gentium Greek on the OLPC at:
Thanks for your continued interest in Gentium!
