Use "ñ" on behalf of username and e-mail
The client has users with the letter "ñ" in their email. We have transmitted the following recommendations:
The registration form does not actually allow this character (ñ), either in the user's name or in their email. The options are:
a) Use an alternative email for registration on the platform
b) Check if the domain can also be registered but with n and have it redirected to the main one (with ñ). This is the recommendation of the Google expert: https://support.google.com/mail/thread/13290908?hl=es
There is a Microsoft page that advises against this practice (https://social.msdn.microsoft.com/Forums/es-ES/bf6c6a16-295e-4c22-b311-25d006ae64e3/envo-de-correos-a-cuentas-con-?forum=winformses)
We have also done a test with the mail at: http://www.comprobarcorreo.com/ and it tells us that the account "info@cualquiercosaconeñe.es" does not seem valid.
However, the customer suggests if we can make the following change from Netex: "If it is for shipping, would it be possible to 'translate' the email to punycode and store it like this to see if it works this way? The result would be "firstname.lastname@example.org".
I look forward to your comments,
