Easy, There are two ways.
1. Dowload XboxToolBoxX from xbins and use it to insert these types of symbols into your xbox name. I dont have the list any more but i remember many.
%a-button
%b-button
%zoom
%crouch
%left-stick
%right-stick
theres many more but you get the idea. It alos possible to get these symbols into your player profile name but i cant get it to work. so i just inserted anscii2 characters
2. the hard way is to grab the nickname.xbn and do the changes with a hex editor. theres a complete list somewhere of all the %commands but i lost the link.
