We get some people who connect and play with names that contain hidden characters or blank names. One guy, it just shows colored boxes for his name because there is some strange hidden character there. How can this be prevented? Thanks.
EDIT: I added this screenshot since I can't copy and paste it -- this is from our logs, the guy who's name contains the colored boxes showing other people how to do it.
I believe its some sort of CTRL+key combination to do this. But I would like to restrict this so people have to have actual names.
