Printing Magento currencies and prices on a PDF

This is a short little post, primarily just to remind me. We need to convert to html entities or symbols like $ and £ won’t print. There are lots of ways of getting the price from the product object, but getFinalPrice seems to be the simplest.

$raw_price = $this->getProduct()->getFinalPrice(); // string "£3,295.00"
$price =  htmlspecialchars(Mage::helper('core')->currency($raw_price,true,false));
