The form shouldn't save at all if it contains an emoji. Are you saying that the form actually saves despite the error notice? If so, that certainly shouldn't be the case (it isn't for me). I'll correctly get the following form error

And the form will have failed to save, so refreshing the page doesn't retain my update.

Looks like the problem is somewhere in our sever setup.
Locally I'm also getting the error notice, but on our servers we are able to save the form.

Just want to confirm that using emoji's in field labels is not allowed, but you shouldn't be able to save the form with the error being raised. From the sounds of your issue, if it's breaking the control panel, the form has somehow been saved despite validation errors, which shouldn't happen.
