              	#   Encoding UTF-16:
              	#
              		#   Encoding of a single character from an ISO 10646 character value to
              	#    UTF-16 proceeds as follows. Let U be the character number, no greater
              	#    than 0x10FFFF.
              	#
              	#    1) If U < 0x10000, encode U as a 16-bit unsigned integer and
              	#       terminate.
              	#
              	#    2) Let U' = U - 0x10000. Because U is less than or equal to 0x10FFFF,
              	#       U' must be less than or equal to 0xFFFFF. That is, U' can be
              	#       represented in 20 bits.
              	#
              	#    3) Initialize two 16-bit unsigned integers, W1 and W2, to 0xD800 and
              	#       0xDC00, respectively. These integers each have 10 bits free to
              	#       encode the character value, for a total of 20 bits.
              	#
              	#    4) Assign the 10 high-order bits of the 20-bit U' to the 10 low-order
              	#       bits of W1 and the 10 low-order bits of U' to the 10 low-order
              	#       bits of W2. Terminate.
              	#
              	#    Graphically, steps 2 through 4 look like:
              	#    U' = yyyyyyyyyyxxxxxxxxxx
              	#    W1 = 110110yyyyyyyyyy
