[swift-users] CharacterSet vs Set<Character>

I was playing with CharacterSet, and I came up with:
let vowels = CharacterSet(charactersIn: "AEIOU")
let char: Character = "E"
That last line doesn't compile: I get "*cannot convert value of type
'Character' to expected argument type 'UnicodeScalar'*"
The problem is, I could not find a simple way to convert from a character
to a unicodeScalar. The best I found is the very ugly:
Did I miss anything? Does it have to be that horrific?
If so, I find using Set much better:
let vowelsSet: Set<Character> = Set("AEIOU".characters)
I must have missed something. Any suggestion welcome
