我无法用某些语言发送电子邮件。我尝试用UTF-8添加content-type。Asi尝试对$body = utf8_encode($_POST['sendmessage'];进行编码，但仍然不起作用。
当我尝试发送

Meu nome é Rick

电子邮件正在发送为

Meu nome é Rick

我的代码是

$from = "xxxxx <xxxxxxxxxx@gmail.com>";
        $to = $_POST['sendname']."<".$_POST['sendemail'].">";
        $subject = $_POST['sendsubject'];
        $body = $_POST['sendmessage'];
        $host = "pro.turbo-smtp.com";
        $username = "xxxxxxxxxx";
        $password = "xxxxxxxxxx";
        $headers = array ('Content-Type' => 'text/html; charset=UTF-8',
        'From' => $from,
        'To' => $to,
        'Date' => date("r"),
        'Subject' => $subject);
        $smtp = Mail::factory('smtp',
        array ('host' => $host,
        'port' => 587,
        'auth' => true,
        'username' => $username,
        'password' => $password));
        $crlf = "\r\n";
        $mime = new Mail_mime($crlf);    
        $mime->setHTMLBody($body);
        $bodyx = $mime->get();
        $headers = $mime->headers($headers);
        $mail = $smtp->send($to, $headers, $bodyx);

任何帮助都很感激。：）
