TYNDALE TECH ALERT: David Instone-Brewer of Tyndale House has sent out another of his useful e-mails on subjects pertaining to computing and biblical studies. This one is on "Greek and Hebrew Fonts - Unicode and older" and can be found on his web page by following the link. This message is very helpful: it seems to tell pretty much everything you need to know to install and use Unicode fonts. Unfortunately for me, one of the things I needed to know (well, really, the one thing I needed to know) is that Unicode isn't available for the Mac at present and may not be for the foreseeable future. That's disappointing, but at least it lets me ignore Unicode and think about other things. Thanks David, and keep up the good work.
UPDATE: Mark Goodacre has comments that will be useful to PC users.
UPDATE (24 April): Guess what? It's not that simple. Mac users go here for more.
