The answer from Baidu is more vivid and impressive, so I will take a note.

1. ASCII codeWe know that in a computer, all information is eventually represented as a binary string. Each binary bit has two states: 0 and 1. Therefore, eight binary bits can combine 256 states, which is called a byte ). That is to say, a single byte can be used to represent 256 different States. Each State corresponds to one symbol, that is, 256 symbols, from 0000000 to 11

In the UCS code there is a character called ZERO WIDTH No-break Space, and its encoding is Feff. Fffe is not present in UCS, so it should not appear in the actual transmission. UCS specification recommended that we transfer the byte stream before the transmission of the character "ZERO WIDTH no-break space." This means that if the recipient receives the Feff, the byte stream is Big-endian, and if Fffe is received, it indicates that the byte strea

multiple encoding methods in the world. The same binary number can be interpreted as different symbols. Therefore, to open a text file, you must know its encoding method. Otherwise, garbled characters may occur when you use an incorrect encoding method. Why do emails often contain garbled characters? It is because the sender and receiver use different encoding methods.As you can imagine, if there is an encoding, all the symbols in the world will be included. Every symbol is given a unique encod

Differences between the two:
The Unicode specification has the concept of BOM. Bom -- byte order mark, which is a mark of the byte order. Here is a description of BOM:
There is a character named "Zero Width no-break space" in the UCS encoding, and its encoding is feff. Fffe does not exist in the UCs, so it should not appear in actual transmission. We recommend that you transmit the character "Zero Width no-break space" before transmitting the byte stream in the UCS specification ". In this way,

As UTF-8 is a 8-bit encoding no BOM is required and Anyu+feff character in the decoded Unicode string (even if it ' s the F Irstcharacter) is treated as a ZERO WIDTH no-break SPACE.UTF-8 is encoded in bytes, its byte order is 様 in all systems, there is no byte order problem, and therefore it does not actually require a BOM ("Byteorder Mark").
