$body = htmlspecialchars($body);

$page.="<div>";
$page.= "<a href='mailto:{$to}?subject={$subject}&body={$body}'>"; 
$page.="</div>";

Answer 1

Use urlencode() on the $subject, $body

$to= "XXX@mail.com";
$subject = urlencode("XXX");
$body = strip_tags($str_body); // use strip tags
$body = urlencode(htmlspecialchars($body));

Answer 2

The behavior of mailto link depends on the browser. There is no way you can influence it. Also you are at the mercy of the special configuration of the client computer : the browser passes the data in the link to the default email account of the default email software. This might work or not.

If you want to have control over the email sent, your page must POST the data on the server and you have to send it using PHP either using the mail() function or a mailer library.
