  class Foundation_API UTF16Encoding: public TextEncoding
   UTF-16 text encoding, as defined in RFC 2781.
 When converting from UTF-16 to Unicode, surrogates are
 reported as they are - in other words, surrogate pairs
 are not combined into one Unicode character. 
 When converting from Unicode to UTF-16, however, characters
 outside the 16-bit range are converted into a low and
 high surrogate.

 Creates and initializes the encoding for the given byte order.

 Creates and initializes the encoding for the byte-order
 indicated by the given byte-order mark, which is the Unicode
 character 0xFEFF.

 Returns the byte-order currently in use.

 Sets the byte order.
                
        void setByteOrder(int byteOrderMark);
 Sets the byte order according to the given
 byte order mark, which is the Unicode
 character 0xFEFF.
