To quote the JLS:

<quote>
The Java programming language specifies a standard way of transforming a 
program written in Unicode into ASCII that changes a program into a form 
that can be processed by ASCII-based tools. The transformation involves 
converting any Unicode escapes in the source text of the program to 
ASCII by adding an extra u-for example, \uxxxx becomes \uuxxxx-while 
simultaneously converting non-ASCII characters in the source text to 
Unicode escapes containing a single u each.

This transformed version is equally acceptable to a compiler for the 
Java programming language ("Java compiler") and represents the exact 
same program. The exact Unicode source can later be restored from this 
ASCII form by converting each escape sequence where multiple u's are 
present to a sequence of Unicode characters with one fewer u, while 
simultaneously converting each escape sequence with a single u to the 
corresponding single Unicode character.

It allow you to use any unicode in names and strings with tools
that does not support those characters.
