I'm using various European characters (like ø, ą, ñ) in my database, but they are not correctly displayed in my php-file. I've tried some things (below) that I found in simmilar questions, but none of them works.
<head>
<meta charset="utf-ISO-8859-1">
...
</head>
<head>
<meta charset="utf-8">
...
</head>
<?php
header('Content-Type: text/html; charset=ISO-8859-1');
echo "øąñ";
?>
