Putting symbols into Title

I work for an organization that uses superscripted registered trademark symbols in much of their content. I need to be able to superscript that symbol in course titles and section headings. I don't have a problem in the body text, but the dialogue box with the superscript option doesn't appear when I highlight text in the course title or section headings. I have tried copying and pasting and using the unicode input. I tested the unicode input tool in Word and it worked fine. I just can't get it to work in Rise. Are there any other work-arounds or any idea when Articulate may make this possible in Rise?
