(NSUTF16StringEncoding data has 2 leading byte order bytes - but why does lengthOfBytesUsingEncoding not take this into it's count?)
The data includes the Byte Order Mark (BOM) 0xfffe (see http://en.wikipedia.org/wiki/Byte_order_mark).
Documentation on -dataUsingEncoding:allowLossyConversion: explains that it is doing that.
