No, that's not the problem. The \catcode primitive requires a  
character number; either "HHHH or `\<character> is a legitimate form  
of <number>.

The actual problem is that TeXShop doesn't seem to allow U+2028 to be  
entered. Hexdump-ing a file, I see that it's converting U+2028 typed  
with the Hex Input method into U+000A in the saved document. Most  
likely this is default Cocoa Text behavior.

I also tried TextWrangler; in this case, my U+2028 was saved as U 
+000D. So again, the editor doesn't allow this character into the file.

If you can get it in there, XeTeX can handle it with active-character  
definitions, as people have suggested; but it looks as though it may  
be more trouble than it's worth!
