what are you asking?

should be set by your browser to always use utf-8 to decode files by default, so there is the phenomenon you mentioned.


I just specially tested it.
if the html file utf-8 does not have bom encoding, charset= "gbk", the browser parsing will still garbled.


I think your utf8 should be encoded in UTF-8 with BOM format.
I also found that UTF-8 is encoded in BOM format, and the browser can parse other codes such as "ISO-8859-1" instead of charset.
