I have problem that when I download the PDF it will download the font together in the PDF which will create a very big size of PDF (about 10mb+).
<?php
include "/dompdf_config.inc.php";
$html =
'<html><body><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<style>
*{ font-family: simsun; }
</style>
<p>开发人员指南</p>
</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("hello.pdf"); ?>

Answer
You’ll want to enable font subsetting.
In dompdf 0.6.2 or earlier set the DOMPDF_ENABLE_FONTSUBSETTING configuration constant to true. Configuration constants can be set in dompdf/dompdf_config.custom.inc.php.
In dompdf 0.7.0 or later after you instantiate dompdf you can configure this option using the set_option method: $dompdf->set_option('isFontSubsettingEnabled', true);.
