Hello, I tried registering an account and when I did I put in special characters for the password. So when I tried connecting it to my wii u I tried putting in the special character, and it wasn’t available to put in. So I tried changing the password but it said I have to connect it to my Wii U first before I can change the password. I just wanted to see if there was a way to change my password to be compatible with the
Wii U, Thanks 
Which special characters were you able to use on the website but not on the console? There is a filter in place for these
