Hi @themacman,
I don’t think you’ll want to embed the superscript directly in your journal title setup field – this field is used not just to present the front-end, but also to describe the journal to multiple third-party services via OAI, XML import/export, etc., and in many of those cases a superscript will garble the data.
I’d suggest using theming to just present the superscript on the front end. How you do this will depend on where and how you want it presented – you’ll probably want to do some CSS work, but also you’ll likely have to override some templates that currently just pull the journal title from setup. There’s some documentation on child themes in OJS over here: OJS 3: Need help with theme customization - #2 by NateWr
