I just tried your example with the latest version of GFSDidot (the older
version I had on my system did not show some diacritics; this problem
disappeared when I installed the latest), and the italics are there, I don’t
see any problem in the pdf. If you want the Greek displayed in Theano, you will
have to add “force=yes” to your definition of the fallback family:
\definefallbackfamily
[mainface]
[rm]
[Theano Didot]
[preset=range:greek,force=yes]
Your text cannot have two main languages, so
\mainlanguage[fr]
If you want hyphenation for your Greek passages, you can add
\setuplanguage [fr] [patterns={fr,agr}]
The line where you have polytonic Greek does not use precomposed characters,
but combinations of greek characters and diacritics; this will probably not
work in recent context versions that expect actual unicode input.
I hope I have really understood what you want: GFSDIdot for the French text and
Theano for Greek?
