Character encoding issue

On email notifications there seems to be a character encoding problem. all   become Â's. I've attempted adding a line of code to set the character but it doesn't seem to be working.

I tested my form notification email and I was not able to replicate your issue. Could you please share the form URL so we can check it further?
