     *   a unicode string.
     * - The minimum sized unicode string is one character (2 bytes) and a
     *   second character for the \0, which is why we have a 4 byte array.
     *   One byte to store the character we wish to print, and a second to
     *   tell OutputString to stop.

     *   function, which is basically what this function needs to emulate.
