[swift-evolution] Character vs. String literals

[Andrew Duncan]

We have all watched the evolution of the String class, and the amazing jockeying required to accommodate Unicode combining characters and the like. At this point, the distinction between Characters and Strings and Arrays of Characters (myString.characters) is becoming clearer.

But in the source code, there is ambiguity. What is "a", a character literal or a string of length 1? I suggest reinstating the C convention of using single-quotes for delimiting Characters.
