I was just really glad it was "Zoe" and not "Zooey". My niece is nothing like a zoo.

Diacritics aren't completely uncommon in the UK - a fairly common name of Welsh origin is Siân (pronounced "shaan"), although as mentioned here my brain doesn't want to pay attention and I always have to check which vowel wears the hat.

I didn't realise Zoe was also the name of a Neil Gaiman pet. At least you're not calling her Cabal.
