请教关于php的iconv编码转换问题

public function file_get(){
        $file = file_get_contents('Curl.html');
        iconv("ANSI", "UTF-8//IGNORE", $file);
        return empty($file) ? null : $file;
    }
}
header("Content-type: text/html; charset=utf-8");
$url = new mycurl();
$file = $url->file_get();
echo strip_tags($file);

Curl.html如下：

输出如下：（乱码!）

Notice: iconv(): Wrong charset, conversion from ANSI' to UTF-8//IGNORE' is not allowed in D:xampphtdocsfunctionfunctioncURLcurl5.php on line 34
