We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Using É, é (e-acute)  in emails.
It looks that É, é (e-acute) symbols are not appropriate for valid email. I used https://pypi.python.org/pypi/robotframework-faker/ which uses this library and the following email was returned: 
andré38@mentzel.net

But email verification was failed for this email. 
Could you remove É, é and other such letters if they are present from valid email generation?

--- END ISSUE ---
