Well - that wpould need compiler support ... which may or may not exist 
in gcc-3 (you'd have to read
the codumentation to find out).

However, one trick is to make use of the fact that quoted strings in 
property-lists have unicode escape
sequences using \U ...

String s = [@"\" \\U0000\\U0001\\U0002\\"" propertyList];

The propertyList method converts a text-based property-list 
representation to it's internal format ...
So the literal string needs leading and trailing '\"' sequences to be a 
quoted string, and the
backslashes within the string must be quoted to allow for the normal 
quoting performed by the
compiler.
