Character encodings

Unicode = UTF-16, not UCS-2.  In practice there is no difference
at the moment, because no 10646 planes other than the BMP (plane 0)
contain any characters.  UTF-16 = Unicode uses surrogate
characters, whereas UCS-2 simply cannot represent the Astral Planes.
Therefore, UTF-16 encoding should be used instead of UCS-2.
