Hmmmm, this is a bit misleading. The fonts do contain Greek  
characters, but do not have OpenType support for the Greek script.  
However, as Greek is a "simple" script, at least in its unaccented  
form or using precomposed accented characters, it can work OK without  
specific OpenType support....

....as shown by the fact that the result is correct.

If you define \greekfont, then I guess polyglossia assumes you know  
what you're doing, and simply uses it. If you don't define this, then  
it attempts to turn on the appropriate OpenType behavior in your  
current font, finds that Greek isn't supported, and complains.

Yes, I agree. In other cases such as Arabic, the error would be more  
helpful, as a font that lacks OpenType Arabic support will not render  
correctly (even if it includes the characters -- yes, there are such  
fonts). But for "simple" scripts like Cyrillic or Greek, perhaps it  
would be better to just write a message to the log, rather than  
actually consider it an error.

François, what do you think?
