I from a 犇 Unicode website know

 
The Universal Character Set USES surrogates to 
The address characters outside the initial Basic 
Multilingual Plane 
Without resorting to wining 16 bit byte 
2048 surrogate representations. By combining pairs of the 
Code points, and the remaining characters in 
All the other planes can be 
Addressed (1024 x 1024=
1048576 code points in the other 16 planes). 
In this way, UCS has a built - In 16 bit encoding 
Capability for 
UTF - 16. These code points are no means 
Into leading or high "surrogates" 
(D800 - DBFF) and trailing or 
"Low surrogates" 
(DC00 - DFFF) In UTF - 16, 
They must always appear in pairs, 
As a high surrogate followed 
By a low surrogate, thus using 32 bits to 
Denote one code point. 

How it use in Unicode?
