How to print Unicode Characters in Swift

Question

I want to print Unicode characters for some special symbol like `,',@,$ so please let me know if there is any method which converts string to unicode characters like \u00e2...

Thanks,

Is it your goal to access the characters of a string, or, given a string of unicode characters, to get their unicode descriptors, e.g. given "â" receive "\u00e2"? — waldrumpus

You can get your string unicodeScalars value, convert to hexa and finish padding it with leading zeros:

extension String { var unicodes: [String] { return unicodeScalars.map{ String($0.value, radix: 16) } } func paddingToLeft(maxLength: Int) -> String { return repeatElement("0", count: max(0,maxLength-count)) + self } }

let str = "\u{00e2}" let hexa = str.unicodes.first! print(hexa.paddingToLeft(maxLength: 4)) // "00e2\n"
