@interface NSString (GTMNSStringUtilitiesAdditions)
// Returns a a UTF16 buffer. Avoids copying the data if at all
// possible for fastest possible/least memory access to the underlying
// unicode characters (UTF16). This returned buffer is NOT null terminated.
// *DANGER*
// Since we avoid copying data you can only be guaranteed access to
// the bytes of the data for the lifetime of the string that you have extracted
// the data from. This exists to allow speedy access to the underlying buffer
// and guaranteed memory cleanup if memory needs to be allocated.
// Do not free the returned pointer.
//
// Args:
// length - returns the number of unichars in the buffer. Send in nil if
// you don't care.
//
// Returns:
// pointer to the buffer. Nil on failure.
