Encryption not working with Unicode #334

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

Run the following PHP code:

<?php

$html = '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<div style="font-family: DejaVu Sans Condensed, monospace; font-size: 11px;">
Персонализиране хедър
</div>
</body>
</html>
';

include_once('dompdf/dompdf_config.inc.php');
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->get_canvas()->get_cpdf()->setEncryption('userpass', 'ownerpass', 
array('print'));
$dompdf->stream('unicode.pdf', array('Attachment' => 1));

?>

What is the expected output? What do you see instead?

Text should read Персонализиране хедър. However, it appears 
as ~20 unreadable characters (can't copy and paste here because of the locked 
permissions).

What version of the product are you using? On what operating system?

I'm running the trunk version on Linux/Ubuntu, PHP 5.3.5.

Please provide any additional information below.

I added the line with setEncryption between the render() and the stream() 
calls, according to this post: 
http://www.dashinteractive.net/dompdf/index.php?v=1702369

If you remove the call to setEncryption, the problem no longer appears (but 
obviously no password protection is enforced either).

It looks like it was fixed in the code from the trunk.

Hmm, it doesn't seem fixed to me. Here's what I did:

$ svn update

Fetching external item into 'dompdf/lib/php-font-lib'
External at revision 38.

At revision 454.

$ svn info
Path: .
URL: http://dompdf.googlecode.com/svn/trunk

Then I ran the code in the original post, opened the resulted PDF and entered 
the password. The result came out as in the attached file.

Am I doing something wrong? Is there any other way to do it?

I am seeing a difference in rendering. Unprotected the document renders as 
expected but when protected I am actually getting the missing glyph box (links 
below). So not even as good as freecorvette. The problem seems to only affect 
renders that utilize embedded fonts. Rendering using the core fonts does not 
appear to exhibit the problem.

FYI, I added an option to password protect a rendered document to the debug 
tester.
