this is because when no greek is present (keep in min dthat we talk of 
fonts with at most 256 chars) the defaults are real stupid defaults just 
to get something ... in enco-def there are definitions like:

\definecharacter greekAlphatonos       {'A}

with luatex there is some more trickery .. trying to find a match using 
the unicode tables but even then if fonts lack the chars ... well .. bad 
luck (if tex would not have math and therefore math greek one would 
never notice the differerences in such defaults)
