How to insert symbols like em dash, ® or ™ in refinerycms

Question

I'm trying to figure out how to add the ability to add symbols like an em dash, ® or ™ in the wymeditor in refinerycms. Looking at the boot_wym.js.erb there doesn't appear to be an option to enable it in the menu. Does anyone know if it is possible and how you would do it?
