我试过了：
1.
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'UTF-8','utf-16');
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'HTML-ENTITIES','UTF-8'); //both lines together
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'HTML-ENTITIES','UTF-16');
但还是显示乱码或汉字
正确显示此 html 的正确方法是什么？
在您的 html 中，如果您看到奇怪的字符，请将字符集 utf-16 替换为 utf-8 或 ISO-8859-1。
$this->bodyHTML = str_replace("charset=utf-16","charset=utf-8", $this->bodyHTML);

我试过了：
1.
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'UTF-8','utf-16');
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'HTML-ENTITIES','UTF-8'); //both lines together
$this->bodyHTML = mb_convert_encoding($this->bodyHTML,'HTML-ENTITIES','UTF-16');
但还是显示乱码或汉字
正确显示此 html 的正确方法是什么？
在您的 html 中，如果您看到奇怪的字符，请将字符集 utf-16 替换为 utf-8 或 ISO-8859-1。
$this->bodyHTML = str_replace("charset=utf-16","charset=utf-8", $this->bodyHTML);
