// Spelling to Phoneme rules for: Ancient Greek

// Preliminary character substitution:
//   Convert tonos, oxia and perispomeni to varia
//   Remove psili (soft breathing)
//   Convert dasia accent to a separate prefix character ("ɦ") NOTE: using U+0266 because it's above eSpeak's Latin character limit of 0x250.
//   Remove iota subscripts
//   Replace Latin characters by same-shape Greek characters
