Python learning----Character Set encoding

1 ASCII code: American Standard code for information Inerchange

The first binary and Character encoding mapping table used in the United States

2 Gb2312, Gbk1.0, Gbk10830

China's first set of coding table Gb2312, only contains Simplified Chinese characters, after the discovery of non-added, and constantly expanded, and the emergence of GBK series coding

3 Unicode, Utf-8

Since countries all over the world have developed their own coding tables, leading to barriers to information exchange between countries, ISO organization came forward to develop a unified global code table, that is, Unicode code, also known as the Universal Code.

Although the universal code includes all the world's characters, but each character is expressed in two bytes, for the English-speaking countries, resulting in a lot of space waste, in order to save costs, the code is compressed, the alphabet is 1 bytes, the European characters in two bytes, Chinese characters in three byte representation

4 the operating system entering China adopts the Gb2312 coding standard developed by China, while UNIX and Linux use the UTF-8 coding standard
