无法重点处理使用我的电子邮件表单发送的邮件。 有人可以帮我一把吗？ 这是我的代码：

This is what the message is showing: Cão açorda água côco teste acentuação

This is what I wanted it to show: Cão açorda água côco teste acentuação

Can someone give me a hand? I would be very grateful.

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if(!empty($_POST['contactname']) && !empty($_POST['contactemail']) && !empty($_POST['contactmessage'])) {
        $to = 'email@gmail.com'; // Your e-mail address here.
        $body = "
NCliente: {$_POST['contactname']}
Email: {$_POST['contactemail']}


{$_POST['contactmessage']}

";
        mail($to, "Mensagem de ", $body, "From: {$_POST['contactemail']}"); // E-Mail subject here.
    }
}
?>

This looks like an encoding problem. If you want to display characters like 'ç', typical from portuguese language, you need to decode your text parameters to the UTF-8 pattern. That way, they are going to be displayed properly.

To do that, you could try using utf8_decode(string) function from PHP. Something like this:

$contactname = utf8_decode($_POST['contactname']);

EDIT: Your code would look like this:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if(!empty($_POST['contactname']) && !empty($_POST['contactemail']) && !empty($_POST['contactmessage'])) {

    //this is the part where you convert to utf8 pattern
    $namecontact = utf8_decode($_POST['contactname']);
    $messagecontact = utf8_decode($_POST['contactmessage']);

    $to = 'email@gmail.com'; // Your e-mail address here.

    $body = "
NCliente: " .$namecontact. "
Email: {$_POST['contactemail']}


". $messagecontact ."

";
    mail($to, "Mensagem de ", $body, "From:" . $namecontact); // E-Mail subject here.
}
}
?>
