How do I type diminished character? "𝇈"

I'm able to print a musical dimnished symbol with the following line of code:

print("\u{1D1C8}") // output:  

However, when I assign that literal to a text field's text property, it doesn't show the diminished character in the text field.

        textField.text = "\u{1D1C8}"

I checked in Xcode->Preferences->Fonts & Colors. There isn't a setting for the font for the debug window, although there are font settings for the editor window.

How do I find a font that would print the diminished character? I have done a search on the internet, and I have tried a few fonts randomly.

I found some fonts that have the diminished symbol in it, but the code to initialize the UIFont object with that font returns a nil. The extension of the font file is ttf, like other font files that I've gotten to work.

        let font2 = UIFont(name: "Maestro Wide Regular", size: 12) // = nil

Anyone have any experience with this?
