<?php
$EmailFrom = "...";

$Subject = "Zpráva s ";
$name = Trim(stripslashes($_POST['name']));
$phone = Trim(stripslashes($_POST['phone']));
$email = Trim(stripslashes($_POST['email']));
$message = Trim(stripslashes($_POST['message']));
// validation
$validationOK=true;
if (!$validationOK) {
print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
exit;
}
// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $name;
$Body .= "\n";
$Body .= "Tel: ";
$Body .= $phone;

You've got two ambiguous parts of your script where character-sets aren't being considered. It's possible your form isn't sending UTF-8 or it's possible you're sending UTF-8 in your email but the client is expecting a different encoding.
I assume you're using a form to post data. Ensure it's set to send UTF-8 from the browser. The strings will now be UTF-8 encoded.
<form action="myform" accept-charset="UTF-8">
You need to add character set and transfer encoding headers to the email header:
$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>\r\nContent-Type: text/plain; charset=UTF-8\r\nContent-Transfer-Encoding: 8bit");
BTW, a faster way to redirect the user is to set the Location header in the response. Use:
header('Location: contactthanks.php')
