Thanks to Rod Decker for reminding me to update some details on my Fonts page. His very useful PDF paper on Unicode has been reworked and retitled:
What a Biblical Scholar / Student Should Know About Unicode
While on that page I also deleted a line about the Tyndale Fonts Kit; there was a problem with the final sigma in that kit, which was the vau/digamma rather than final sigma proper, but it was fixed after David and I had some interesting email exchanges on the topic several months ago. It's a good one-stop solution for your font needs, though in the long run we are all going to be using unicode so the sooner one gets used to it, the better.
