Superscript in app name defined in config.xml

Is it possible to have something like: “< name >AppName< sup >®< /sup >< /name >” - already tried that and not working but just for instance

Have you ever seen an app with such a name in the stores?

I don’t need to upload on store, just asking if it’s possible, a customer want this.

This was me trying to lead you to an answer:

Did I ever see such an app?
Hmm no, I have never seen an app usin a character like that.
Probably not doable.

I think the “®” might technically work (although probably not accepted by the stores), but the HTML code surely not.

® works but it’s not superscript. Anyway thanks!
