I intuitively expected some trash like that from Adobe which is why I wrote "every PDF viewer" and not "Acrobat Reader".

  His "breakout" demo works in Chrome's viewer as well (and obviously FoxIt).

Even better, every font renderer does! A couple of the PDF-based jailbreaks for iOS were actually bugs in the virtual machine used by font renderer to allow fonts to do programmatic hinting, and the PDF only really existed as a container to deploy the font and force it to deterministically render exactly what was required.
