[swift-users] \r\n is one Character

[zhaoxin肇鑫]

​For a new line, Unix uses LF, Classic Mac uses  ​CR, Windows uses  CRLF.
They both means the CR in Unicode.

let str = "\r\n"

str.characters.count // 1

str.lengthOfBytesUsingEncoding(NSUTF8StringEncoding) // 2

str.unicodeScalars.first!.value // 13
