mb_substitute_character(0x3013);Note:
If you want to output some binary data such as image from PHP script with PHP 4.3.0 or later, Content-Type: header must be send using header() before any binary data was send to client (e.g. header("Content-Type: image/png")). If Content-Type: header was send, output character encoding conversion will not be performed.
Note that if 'Content-Type: text
mb_substitute_character("long");
echo mb_substitute_character();
?>
