It’d be nice to be able to do superscript characters, or have a styling dropdown box that enables it to be applied. It works on some characters, as I’m able to type a trademark in superscript using an alt+number code, but when I do the same with a registered mark ®, it comes through as normal text, not superscript.
Hi @andrew.gentry, please find this help center article about text assets, and try using the rich text asset instead of the normal text asset. If still no luck, I suggest you try reaching to our support team. 
Best wishes,
