Those wouldn't go into the NSString; they're the byte-order-mark that 
prefixes the UTF-16 data, not part of the character data itself.

I really recommend you write out the string in UTF-8 instead, as I 
suggested yesterday (with example code). UTF-8 is the most common 
modern encoding for text, because (a) it's a superset of ascii, and 
(b) for Roman alphabets it's up to twice as compact as UTF-16.
