Here, I will take a closer look at how python can process different languages. One thing to note is that when Python needs to perform encoding conversion, it will use internal encoding. The conversion process is as follows:Original encoding-> internal encoding-> destination EncodingPython uses Unicode internally, but the use of Unicode needs to consider its encoding form

sat together and shoot their heads to come up with a method: all the characters in the language are represented by the same character set, this is Unicode. The original Unicode Standard UCS-2 uses two bytes to represent a single character, so you can often hear Unicode uses two bytes to represent a single character. But soon some people think that 256*256 is too small, or not enough, so there is a UCS-4 st

Text files usually identify their encoding methods through the first two bytes, but UTF-32 encoding uses the first four bytes to identify their encoding methods. The following are some encoding format identifiers: Encoding Method First few bytes ANSI No format definition Unicode FF fe Unicode big endian Fe FF UTF-8 EF bb UTF-16/UCS

With the launch of the gb18030-2000 national mark, it will fulfill its historical mission in the near future.Gbk encoding is a new Chinese encoding developed in mainland China and equivalent to the ucs to expand national standards.

subsequent code values are affected.Because the network transmission is easy to damage the byte stream, once the byte stream is damaged it is difficult to recover.Utf-8 is more suitable for the network transmission of characters using a single byte of storage, the Chinese characters using three bytes , the other single-byte damage will not affect the other characters, in the coding efficiency between GBK and utf-16, coding efficiency and security of the balanceSo Utf-8 is the ideal Chinese cod
