No garbled characters were found after testing.

Is it a matter of character?

You have not set character encoding here, and the browser will use its own default encoding.

If your file encoding is the same as that of your browser, no garbled text will be displayed. if the file encoding is different, no garbled text will be displayed.

You 'd better set the file encoding, so the browser will know which encoding method is used, so that no garbled characters will be involved.

You can check the encoding of the program file, and use the header function to set the encoding for viewing in the browser.

It mainly depends on what kind of garbled code you are using. There are many possibilities for garbled code.

Check whether the file encoding is consistent with the browser encoding.
