Yes, if you read Xzin's 10 box sticky he mentions using unicode. If you examine the character map feature of windows you will see that the codes alt-161 -> alt-255 are available and are functional for wow. These are the characters you see on toons names that piss you off because you normaly can't type them without the character map.

Those character don't have to be blocked (or require a white list) if you use them properly on macro/spell bindings.

I had a binding map all set up for the Xkey pro but had to erase it and use the modifiers instead. Once I get the programmer I will use the unicode method.
