[swift-evolution] Proposal: Make it easier to use unicode identifiers in Swift.

[肇鑫]

let unicodeScalar = UnicodeScalar("α") // 945

unicodeScalar.dynamicType // UnicodeScalar.Type


var unicodeScalars = "This is α".unicodeScalars // "This is α"

unicodeScalars.dynamicType // String.UnicodeScalarView.Type


let u1 = unicodeScalars.last! // 945

u1.dynamicType // UnicodeScalar.Type


let values = unicodeScalars.map({ $0.value })

values // [84, 104, 105, 115, 32, 105, 115, 32, 945]

values.dynamicType // Array<UInt32>.Type


let range = Range(start: unicodeScalars.endIndex.predecessor(), end:
unicodeScalars.endIndex)

let beta = UnicodeScalar(unicodeScalar.value + 1) // 946

unicodeScalars.replaceRange(range, with: [beta])

unicodeScalars // "This is β"
