You can see that practically every word has some blanks where letters should be.

Note that Adobe Reader (11.0.09) does a _better_ job of rendering but still has many missing characters, and throws up an error message about a font that it "cannot extract", so the PDF itself may be ill-formed (in which case pdf.js should give an error message too).
