No explanation on invalid characters on registration form
|Reported by:||molnarm||Owned by:|
When a user tries to register with a username containing special characters (e.g. accented letters), WP shows an error message saying "This username is invalid because it uses illegal characters. Please enter a valid username.".
However, this doesn't really help the user because the message does not explain how to fix the problem, i.e. which characters are allowed.
Please consider adding a brief listing of allowed characters.
