Thanks for making this available! I looked at it and it seems like a  
few further changes are in order for full Unicode compatibility. I'm  
attaching a copy with further modifications as follows:

* use U+02BC MODIFIER LETTER APOSTROPHE for the apostrophe (elision),  
not ''

* use U+2060 WORD JOINER as compound word mark, not the letter "v"

* update rules for hiathi to recognize letters with dieresis, not  
following double-quote

Most of these are probably rare in practice, but I think this more  
closely reflects how Greek text in Unicode should be encoded.

One further issue to consider would be composed vs. decomposed text;  
this file uses precomposed letters for the vowels with tonos or  
dieresis, but these could also be encoded as sequences of vowel +  
diacritic. So additional rules should be included to recognize those  
forms as well. This is left as an exercise for the reader.... :-)
