Text Wrapping not happening as it should in NSTextField Attributed String

Question

I am having an issue with text not wrapping correctly if there is a single quote, or macOS ASCII Extended Character #213 (shift+opt.+]) in a string.

Apple does not escape the media item title string when it is retrieved through the iTunesLibrary framework.

As you can see in the example below, the first string is exactly how it come from the iTunesLibrary using the framework API call. The second string is is the single quote is escaped, the third string is if I use macOS Extended ASCII Character code 213, and the fourth string is if I use a tilde. The tilde is not the right character to use in this situation, but it is the only one that correctly wraps the text in the cell.

I've been working on this for the past 6-8 hours to figure it out and I'm just throwing it out there to see if someone can help me.

VerticallyCenteredTextFieldCell.swift

import Cocoa

class VerticallyCenteredTextFieldCell: NSTextFieldCell {

    // https://stackoverflow.com/questions/11775128/set-text-vertical-center-in-nstextfield/33788973 - Sayanti Mondal
    func adjustedFrame(toVerticallyCenterText rect: NSRect) -> NSRect {
        // super would normally draw from the top of the cell
        var titleRect = super.titleRect(forBounds: rect)
        let minimumHeight = self.cellSize(forBounds: rect).height
        titleRect.origin.y += (titleRect.height - minimumHeight) / 2
        titleRect.size.height = minimumHeight
        return titleRect
    }
    
    override func drawInterior(withFrame cellFrame: NSRect, in controlView: NSView) {
        super.drawInterior(withFrame: adjustedFrame(toVerticallyCenterText: cellFrame), in: controlView)
    }
}

This is the result I get: Anyone else get the same result running this?
