I just wrote a page for my new website on Hebrew and Greek fonts for students and scholars. Until my new website goes live, the link to the article is https://three-things.ca/codex/biblical-fonts.html; once my new site is live (which I hope is soon), then the link should be https://three-things.ca/biblical-fonts.html.
Let me know what you think.
I would have included Gentium in the Greek fonts. Its range covers the majority of characters in all Indo-European Scriptures.
You mention the SIL fonts for Hebrew and Greek, but not the Charis SIL unicode font for transliteration. I find it a lovely font visually, and it includes all the diacritics a semiticist could want (I think). Mac users may want the SIL Hebrew-Greek Transliteration Unicode Keyboard to use with Charis SIL.
