Reading foreign characters in a CSV file - php

Question

I have a script that takes a CSV file and uploads each row to a database. However, foreign characters in the file not just display wrong, but don't display at all.
For example, here is an "input" row, and what it would read like in the database:
"This café is amazing", "1000", "www.example.com"
"This caf", "1000", "www.example.com"
This is the script that does the upload:
header("Content-Type: text/plain; charset=utf-8");
if (!isset($_POST['form_id'])) {
header("Location: ./?error=form_id");
exit();
}
$form_id = $_POST['form_id'];
$csv = $_FILES['csv_file'];
if ($csv['size'] > 0) {
$handle = fopen($csv['tmp_name'], "r");
require_once("db.php");
$i = (!isset($_POST['csv_headers']) ? 1 : 0);
while ($data = fgetcsv($handle, 1000, ',', '"')) {
if ($i > 0) {
$data[2] = str_replace(" + ", "+", $data[2]);
if (strpos($data[3], "http") === false && $data[3] != "") {
$data[3] = "http://" . $data[3];
}
mysql_query("INSERT INTO exhibitor_lists SET form_id = $form_id, company_name = '" . addslashes($data[0]) . "', country = '" . addslashes($data[1]) . "', stand_number = '" . addslashes($data[2]) . "', web_address = '" . addslashes($data[3]) . "', logo_file = '" . addslashes($data[4]) . "', added_date = NOW()");
}
$i++;
}
} else {
header("Location: ./?error=csv_file");
exit();
}
mysql_close();
header("Location: ./?success=upload");
exit();
Even when setting the content type header(), I get the problem.

Save the CSV file in UTF8 before uploading it.
