It works fine if,you set your main font to something including Greek, e.g. Brill. All you're missing in that case is correct hyphenation. Alternatively, you can set a font by Unicode range rather than language (it doesn't do this automatically).

Yes, exactly. I was wondering about the case where your preferred font either lacks the Greek (or whatever unicode range) entirely, or has Greek you don't like the look of.

It strikes me that what we really need is a filter that would tag languages in Pandoc output based on best guesses (Word does this to some extent already). Should theoretically be possible with the language detection libraries out there.

And that was the other part of my query. :-)
