Hi, when an user wite some in the contact form and contain accents or the special caracter "ñ", the message don´t show well. Same problem is if I update the order status in the admin and send an email to the customer.
select Spanish language in your admin and calalod, ande send a message from catalog to admin and other from admin to email destination, and write this words for example:
Sí soy español
the result not is the same in destination.
