Chinese character coding is distinguished from other encodings that the highest bit of Chinese character coding is 1. 0x80 in the computer is represented as 1000 0000 This program is often used to determine whether the current character is a Chinese .& is the bitwise AND, corresponding to the 1 o'clock is 1, the other cases are not 0. such as: 1010 1011 & 1000 0000 = 1000 0000 i.e. a&0x80
