My first team was a-,b-,d-,elaire and captn. The second is all Æteam with accents on the e. I have not noticed any increase on people calling out clones or hacks by mistake.

What I have noticed though is that I have trouble telling my characters apart myself, in particular if the window is resized.
Also, with two irregular chars in the name, I am usually not mailing anything to these chars and trade instead. =]
