[Plugin: Register Plus] single quotes email address

I have an email id having single quote example(this’[email protected]).
Register Plus dosen’t allow this format.
How can I solve this?
I am very sure this format is allowed in email address

RFC 2822
https://tools.ietf.org/html/rfc2822#section-3.4.1

Apostrophes are allowed.

Any of you have any solution, Please share here. Thank You
