Thanks for your answer! Yes, I know about the diaeresis, but I think it could be zo-AY anyways. Just as
Zoe could be so-AY or SO-ay as well. It depends on where you live. I'm French/German and in French Zoë is pr. zo-AY. In Germany we use both, ZO-ee and zo-AY for
Zoe and usually zo-AY for Zoé and Zoë.
Yes zo-AY is the French pr. But it isn't really an AY sound more like a mixture of an AY and an EH but really hard to explain :P
I really like the diaeresis but you're right, it could cause some trouble. I'd have to think about it some more.
