Apostrophe in Email Addresses Prevents Access

We'd like to post the request for apostrophe's to be recognised in customer email addresses. Unfortunately, this is rendering our widget unusable for customers with these characters in their email addresses.

We use identify/prefill to pull through the customers name and email address automatically in the web widget, however, where they have an apostrophe they physically cannot submit their query or join Live Chat, meaning the product cannot be used and is impacting on the quality of our support platform.

Can this please be looked into please, as it does render elements of zendesk not fit for purpose?
