I'm aware of that and think it's a shame. When you need a Character, you either
need to declare the variable with type:
let c: Character = "a"
or use the initializer (which I prefer):
let c = Character("a")
--- but here, this is valid:
let c = Character("ax")
and will compile, yet crash at runtime.
I really hope that special syntax (single-quotes, or any other) is introduced
back in the future.
