UTF-32 stores each character in 4 bytes to ensure that the UCS is fully represented. However, the number of characters in the UCS does not need to be represented by 32 bits at all, UTF-32 greatly wasted space. In addition, because of the combination of characters, the fixed length is not as fast as expected to locate characters, anyway, is super bad.UTF-16 maps the UCS to a 16-long integer for data storage

UNICODE
Unicode name "Universal Multiple-Octet Coded Character Set", short for UCS, is a Set of Character encodings maintained by international organizations. The UCOS assigns a unique code point (code point) to each character, which is usually expressed as U + xxxx, where xxxx is the corresponding hexadecimal code value.
The UCS has two formats: UC
We often say that Windows 95/98 is in a 16 or 256 color state, which means the maximum number of colors displayed on the screen.
You can see that it is normal to display black-and-white text or simple color lines in 16 colors, but if we want to see more than 16 colors, you have to use 256 or more colors. That is to say, you need to set the display mode to a high

The hexadecimal number is a representation of an integer that is often used in programming. It has
0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f a total of 16 symbols, representing 0 to 15 of the decimal number, respectively. The hexadecimal Count party

Function Description: Enter two sets of 16-bit binary code to simulate two 16-bit binary integers, and to find the difference and 16 output.
Basic algorithm: Using complement, simulate the second mechanism subtraction (additive similarity), the difference (complement) is converted to the original code, and then converted to hexadecimal and output.
