Hello,

I have a weird issue related to pdf file generation using zend_pdf.

I am using ZF 1.11.11-minimal.
Linux Debian 6.0.3
PHP Version 5.3.3-7+squeeze3

I saw some php warning errors in apache's error.log.
The warnings are as below:

[Fri Oct 21 16:43:03 2011] [error] [client xxx.xxx.xx.xxx] PHP
Warning:  mb_convert_encoding(): Illegal character encoding specified
in /var/www/...path.../ZendFramework/1.11.11-minimal/library/Zend/Pdf.php
on line 1250, referer: http://domain.com/folder/etc

And these are some lines from pdf generation code:

LINE 1: LINE 1: $pdf = Zend_Pdf::load($templatePdfFile);
LINE 2: $font = Zend_Pdf_Font::fontWithPath($pdfFontPath);

LINE 3: $pdf->properties['Title'] = "Form - PDF"; <-- causing error
LINE 4: $pdf->properties['Author'] = "APPLICATION"; <-- causing error

When I comment lines 3 and 4, there is no warning. But when I
uncomment these lines, I again start to see the php warnings.

I tried to search the error but was not successfull to find something useful.

Anybody has an idea?

Thanks
scs
