RW is supposed to handle all text in Unicode and in my testing, which admittedly hasn't been more than cursory it does. It certainly has no problem with any of the symbols in a couple of my Unicode fonts that I've tried.

You should keep in mind that this is based on the HTML standard and on the installed fonts on the machine rendering the text so when exporting a realm do not expect things like nonstandard scripts like Elvish or Klingon which have unofficial Unicode pages to appear correctly.
