SOLVED: Dompdf Error : Warning: mb_convert_encoding() [function.mb-convert-encoding]:

[ontarget]

Hi
I am trying to get a pdf output using the dompdf 0-6-0beta 3 library I am using Joomla 3.2.0
The error I am getting is
Warning: mb_convert_encoding() [function.mb-convert-encoding]: Illegal character encoding specified in libraries/dompdf/include/dompdf.cls.php on line 412
Unable to stream pdf: headers already sent

Here is the code on those lines

if ($encoding !== 'UTF-8') {
    $str = mb_convert_encoding($str, 'UTF-8', $encoding);
    }

Does anyone know the fix for this issue?
Thanks

Ok the solution everybody has been waiting for...
in the component/component_xxx/views/tmpl/default.php

<tr>
            <td width="100" class="key title_cell">
                <?php echo  JText::_('EB_EVENT'); ?>
            </td>
            <td class="field_cell">
                <?php echo $this->event->title ; ?>
                <div style="display:none;">&</div>
            </td>
        </tr>

The title which the pdf was being named didnt like certain characters so this was placed there <div style="display:none;">&</div>

Upgrade to joomla 3.3.6
The pdf output for my Event Booking pdf stops working
To fix the issue I
Unzipped the latest dompdf library https://github.com/Fabrik/fabrik/archive/joomla3.zip
Remove/rename your libraries/dompdf replace with new zip version

Replace line 3105 dompdf/lib/class.pdf.php




with

$output = ob_get_clean();
if ( headers_sent()) {
echo $output; }

Updated the copy of (in this case Event Booking) file from
components/com_eventbooking/views/registrant/view.html.php and created
components/com_eventbooking/views/registrantpdf/view.pdf.php


Updated
components/com_eventbooking/views/registrantpdf/tmpl/default.php

Line 2: ob_start();

Also make sure your code is tidy and remove any unnecessary spaces

It now works fine again!
