17793	No explanation on invalid characters on registration form	molnarm		"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."	defect (bug)	new	normal	Awaiting Review	Users	2.1	trivial		has-patch	kpayne@… mdhansen@…
