Fixing: E-Mail addresses with special characters are not working. Changed the mail address to match the original input for the validator, add user and update user.
Made in correspondence to and fixes #11796
Thanks for the PR @Kallaen :+1:
(when reviewing the PR, since it will now allow for some XSS prone characters, we should specifically look for XSS injections in the email address)
Thanks for the reply. Yea, I saw the test failing. I'll look into it again.
