These combinations would never arise in an ancient text (perispomenon
occurs only on long vowels, but omicron and epsilon are always short).
I don't know why WinGreek makes allowance for them (perhaps those who
originally defined it weren't fully informed about what was needed?),
and I don't imagine any classicist would be bothered if they were just
turned into omicron and epsilon.  

That would mean that a document in WinGreek encoding might not
translate completely when turned into Unicode (nothing now prevents
someone from making use of these 'impossible' characters).  That's
already true anyway for translating a document from WinGreek to TeX,
if the translation depends on the ibycus package (though one could
always hack ibycus to include the impossible combinations).  What
happens to epsilon-peri, etc., now in cgreek?
