Update Character Error Logic to Allow Characters that are not Emojis

It appears the updates made to present errors prior to submitting a campaign with emojis are too strict. Characters like a registered trademark, check marks, and other characters are generating the error that prevent submitting campaigns, but in the past they didn't generate errors like emojis do. It would be great if the new filters to prevent the errors could be less strict to allow supported characters.
