dtgreene: Or alternatively, you take the next Unicode code point, which is Ϊ (uppercase) or ϊ (lowercase). (This is apparently an iota with two dots above it.)
Sorry, but that remains the letter ι, just noted as been a separate letter and not part of a two letter one (αι, ει, οι). So while αι is pronounced like ε, αϊ is pronounced as two distinct vowels. Same as french accented letters, they don't count as additional letters of the alphabet.
