Solving the problem of garbled characters in UTF documents

In the Unicode state of the browser, I saw such a garbled code. I tried to use PHP to decode it, but it failed... However, a simple file encoding conversion was successful. The steps are as follows:

Keep the content in Western (ISO8859-1) format

Open it with a browser, set the encoding to GB2312, and complete

The problem is this, if my file must Using UTF8 encoding, how to decode this garbled code?

The garbled content is:

'²»ÖªµÀÕâÑùµÄÖ÷»ú¡£'

PHP extension iconv is used for encoding conversion.

The transcoding method is:

$text = iconv("ISO-8859-1", "UTF-8", $text)

The answer is not that simple. I just tried it. The correct solution is like this

var_dump($str = iconv("UTF-8", "ISO-8859-1", '²»ÖªµÀÕâÑùµÄÖ÷»ú¡£'));
var_dump($str = iconv("GB18030", "UTF-8", $str));

First decode to ISO-8859- 1. However, it is still garbled in this state, so it needs to be converted to GB18030, and then restored to UTF-8 (the encoding that matches the file where it is located).
