Create IBInspectable for Unicode Character

Question

I created some icons using websites like ( http://fontastic.me/ ) which gives you a .ttf file.

you can use it

myLable.text = "\u{e002}" //
print("\u{e002}")     //
print("\u{1F496}")   //💖

this works well, but I want to pass the line directly using the storyboard.

Then I start working with a subclass of UILabel and create @IBInsectable for the unicode string. but it didn’t work. following IBInspectable code.

@IBInspectable internal var myString: String? {
        didSet {
            text = "\u{e002}"       //          this works
            text = "\\u{\(myString)}" //\u{e002}    this not
        }

or

let myString = "e002"
print("\\u{\(myString)}")   //\u{e002}

even this also doesn't work

print(myString)
text = String(UTF8String: myString!)

but it will only print text that would suggest printing an icon, for example print("\u{e002}"). How to decide what I am missing?

in advance for help.

            var code: UInt32 = 0
            scanner.scanHexInt(&code)
            let unicodeString: String = String(format:"%C", UInt16(code))
            print("unicodeString: \(unicodeString)")

            text = unicodeString
