Convert unicode symbols \uXXXX in String to Character in Swift
You can use \u{my_unicode}
:
print("Ain\u{2019}t this a beautiful day")
/* Prints "Ain’t this a beautiful day"
From the Language Guide - Strings and Characters - Unicode:
String literals can include the following special characters:
...
- An arbitrary Unicode scalar, written as \u{n}, where n is a 1–8 digit hexadecimal number with a value equal to a valid Unicode code point
You can apply a string transform StringTransform
:
extension String {
var decodingUnicodeCharacters: String { applyingTransform(.init("Hex-Any"), reverse: false) ?? "" }
}
let string = #"Ain\u2019t"#
print(string.decodingUnicodeCharacters) // "Ain’t\n"
