Client struggled to set password on a new OneClick account on the account creation page for multiple days because they were using the £ symbol.

Message they had was just "special symbol". They were confused because they were using one and so thought they were doing it correctly. This issue is simple, the error message is vague and there isn't any instructions on the page as to what symbols are/aren't allowed.

Interestingly when a OneClick user is going through the password reset process and they use an invalid symbol there the error that is displayed is "The password contains invalid characters", still a little vague as there is still no instruction on the page as to what characters are/aren't allowed but better nonetheless.
