ASCII codeWe know that inside the computer, all the information is ultimately represented as a binary string. Each bits (bit) has 0 and 12 states, so eight bits can combine 256 states, which is called a byte. In other words, a byte can be used to represent 256 different states, each of which corresponds to a

The implementation method of UTF-8 coding through javascript, javascriptutf-8 Javascript character set: Javascript programs are written using the Unicode Character Set.

: This article mainly introduces the differences between UTF-8 and UTF-8 without BOM. if you are interested in the PHP Tutorial, please refer to it. BOM -- Byte Order Mark, which is a Byte Mark 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 th

Bom--byte order mark, which is the byte-order mark There is a character called "ZERO WIDTH no-break SPACE" in the UCS encoding, and its encoding is Feff. Fffe is not a character in UCS, so it should not appear in the actual transmission. The UCS specification recommends that the character "ZERO WIDTH no-break SPACE" be transmitted before the byte stream is transmitted. This means that if the recipient receives Feff, the byte stream is Big-endian, and if Fffe is received, it indicates that the b
