Special Characters / Symbols

May 16, 2012 at 11:12 PM

Has anyone been able to insert special charcters into a dynamically created PowerPoint presentation?  I've tried everything I can think of - utf_encode, html_entity_decode.   I need to output symbols such as less than or equal (≤) and alpha (α), but have had no success.

Thank you in advance!

I had this issue, it is actually due to the character encoding on the XML files being written out to the presentation. As a quick and dirty fix for slides, I changed line 230 in ./Classes/PHPPowerpoint/Writer/PowerPoint2007.php from 

$objZip->addFromString('ppt/slides/slide' . ($i + 1) . '.xml', $this->getWriterPart('Slide')->writeSlide($this->_presentation->getSlide($i)));


$objZip->addFromString('ppt/slides/slide' . ($i + 1) . '.xml', utf8_encode($this->getWriterPart('Slide')->writeSlide($this->_presentation->getSlide($i))));

Once I've done a bit more testing & take a look at other possible areas where this is needed, I'll upload as a patch.

Hey hi

I had already inserted special characters, y just modify the file RichText.php


    public function createTextRun($pText = '')
        return $this->_richTextParagraphs[$this->_activeParagraph]->createTextRun($pText);




    public function createTextRun($pText = '')

        return $this->_richTextParagraphs[$this->_activeParagraph]->createTextRun($textoRecibe);


And in the ppt php whe you need to put a text with special character just put this:


$textRun = $shape->createTextRun(utf8_decode('Administración'));
