email received from Form

Hello,

I receive a text by email via a contact formular with bad words: exemple "Lagão" on contact form, I received "lagão".
Also, on textarea, if the customer write several lines (if he go to line), I also would like to receive several lines (not all in one line).
Here is my files.
Many thanks in advance if you can help.

main issue solved by adding on form.php:

$mail->MsgHTML(nl2br($body));
$mail->CharSet = "UTF-8";
$sendEmail = $mail->Send();

Just on email received now with a lot of spaces (see screenshot)
