OK, that makes sense. I'll play with it, but having a few choice pages on the wiki would be great!

OK, I'll write something for German and English, but the thing is that we need more input what users expect. For mixtures with foreign languages, there might not be generally accepted rules at all, so people will define something on an ad-hoc basis.

For Greek: I just looked at a dozen books here on my shelf. Most English books have a separate index for Greek terms; when they sort Greek terms with English words, they use transliteration. The problem with polytonic Greek is that so many different unicode characters need to have the same sort entry. If I ever see the necessity of setting this up, I'll be in touch off-list, but it's such an unusual thing that I think you shouldn't bother now.

All best
