Yes. The surrogates use a pair of 16 bit numbers to represent a
character. The first number is in the range 0xD800 to 0xDBFF and the second
in the range 0xDC00 to 0xDFFF so you get 0x400 * 0x400 = 0x100000 = 1048576
characters although some must not be allowed as one reference says only
917,504 are possible.
