^^^^ followed by 4 (lowercase) hex digits represents a single  
codepoint in the range U+0000..U+FFFF. This is a conversion that  
XeTeX does during the text input process, before things like macro  
expansion; the entire 8-character sequence is replaced by the single  
code it represents, and then processed just as if that code had been  
present in the input.

Does that help? Not really sure what kind of information you're after...
