Cannot register with non-ASCII content in form

[rene-armida]

Validation rules fire that prevent the entry of non-ASCII content into the registration form. See the attached image.

This may be specific to the wrapping site, or may be part of the djaodjin-saas core. I'm not certain. It should be the case that the registration form instead allows non-ASCII input.
