Mathematical symbols not rendered

Some mathematical symbols are not rendered at all, not even showing an empty rectangle or something similar. For example, the following document: http://www.jmlr.org/papers/volume7/belkin06a/belkin06a.pdf in page 7 contains a delta symbol (traingle pointing upwards), which is rendered correctly in Adobe's PDF reader or chrome's built-in PDF reader, but on not software based on Poppler (such as Okular).
