Could I get a screenshot of what you mean "barfs"?  
 
 sure.. were raiding in a nour or so..  will do it then..
but in a nutshell, when the addon frame is up, and "rolls" is selected, players with special characters in their names are shown properly... but when one of them rolls, the addon displays a new member with all characters trunkated up to the specia character... EG:
too name Paws  (A is a special a)  would be ws
Accept (with the special a) would be ccept
etc...
