I\'m generating the csv file with the following header commands:
header(\"Content-type: text/csv; charset=utf-8; encoding=utf-8\");
header(\'Content-Disposit
Use utf8_decode() - WORKED FOR ME
Output 0xEF 0xBB 0xBF
before emitting the CSV data. Don't forget to increase the content length header by 3 if you handle it.
header('Content-type: text/csv;');
header('Content-Length: ' + strlen($content) + 3);
header('Content-disposition: attachment;filename=UK_order_' . date('Ymdhis') . '.csv');
echo "\xef\xbb\xbf";
echo $content;
exit;
header("Expires: Mon, 26 Nov 1962 00:00:00 GMT");
header("Last-Modified: " . gmdate('D,d M Y H:i:s') . ' GMT');
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
header('Content-Type: text/csv;');
header("Content-Disposition: attachment; filename=".$savename);
echo utf8_decode($csv_string);
