�����﷨����ȷ��

Where should the encoding be set? I want to temporarily set up the Chrome browser to view the content, but the encoding setting option is not found in version 60.

Solution:

1. Chrome no longer has this function.

If you are writing PHP, it is recommended to analyze $result first. The browser is a terminal, and you still have to check the source code in the end.

Set header("content-type:text/html;charset=utf-8") to ensure that it is not a problem with PHP output

2. First: When garbled characters appear, please encode the program: File encoding, database encoding, output encoding, etc. It is best to use uniform ones.

Secondly: The new version of chrome has removed the function of setting encoding because the frequency of use is too low. You can modify the encoding by installing an extension: Charset
