Hello cavaliercarey,
Thanks for reaching out using Apple Support Communities!
We understand you're seeing some punctuation issues on your iPhone; we want to help get to the bottom of this.
To learn more, did you make any other changes when you first noticed this being an issue?
Are you using the latest iOS version when this happens, or do you have any pending updates?
Have you tried a normal restart to see if the same thing happens after?
We’ll proceed accordingly to further isolate and resolve the issue you're seeing.
Cheers!
