The difference between GB2312,GBK and UTF-8

GBK

The GBK contains all Chinese characters, and the text encoding of the GBK is double-byte, meaning that both Chinese and English characters are represented by double-byte, except that the highest bit is determined to be 1. As for the UTF-8 encoding, which is used to solve the international character of a multibyte encoding, it uses 8 bits (that is, one byte) in English, the Chinese use 24 bits (three bytes) to encode. For forums with more English characters, you can save space with UTF-8 . GBK contains all Chinese characters, UTF-8 contains the characters that are needed for all countries in the world. GBK is a standard that is compatible with GB2312 on the basis of national standard GB2312. UTF-8 encoded text can be displayed on a variety of browsers that support UTF8 character sets in various countries. For example, if it is a UTF8 code, it can display Chinese in the foreigner's English ie, without requiring them to download IE's Chinese language support package. For a more English-speaking forum, use GBK to occupy 2 bytes per character, while using UTF-8 in English only takes one byte.
