How to insert strings using proxy.insertText that include brackets “( )” in Swift

I'm trying to building a custom keyboard in Swift that does one thing and one thing only.. insert ¯(ツ)/¯upon pressing a button in a keyboard.

This is the function that I have:

func buttonPressed() {
// A proxy to the text input object that the custom keyboard is interacting with. (read-only)
var proxy = textDocumentProxy as! UITextDocumentProxy

// Insert a character into the displayed text.
proxy.insertText("¯\_(ツ)_/¯")
}

The issue is that I keep on getting the error "Invalid escape sequence in literal"

Is there a simpler way to get around this?
