Hmm, unless memoir does something funny, fontspec should be loaded
first. It's the second line in the Latex source (right after the doc

I thought about that. I may be using an incomplete font. It's Minion
Pro. I'll double check with another font with more complete coverage.
But:  the Greek text entered as ERT displays fine. Does that mean that
latex (babel?) switches to an alternative font when it sees the
\textgreek command?

Ok, I'll file a bug report. But what is the bug, exactly? Something like:

"Lyx should not escape symbols when using T1 font encoding"?

Lyx actually inserts a \foreignlanguage{polutonikogreek}{...}. Is that

I'll have to try these ones too.
