I ran into a similar problem with the double left angle bracket while 
trying to append a DOM-style error message in a JavaScript class. The 
instructor told me it would be necessary to use the escaped Unicode 
equivalent for that character. It worked beautifully. You might try it 
here: It would be \u00A0 for the non-breaking space.
