There are 68 of them on the Basic Multilingual Plane.  But many
characters in other planes involve such 16-bit code units.  For example,
all of U+10000 to U+103FF are encoded as D800 DC00 through D800 DFFF.
Currently there are 622 characters in this range alone, and the number
will probably grow.

Google reports over 3 gigahits for this character.
