> Copied from PDFBOX-399:
> Submitting a patch for ignoring badly-formatted CMap ToUnicode instructions.
> This allows parsing of some ToUnicode resource streams that would otherwise throw exceptions which were silently consumed. This allows text extraction to get the correctly mapped characters.
> Specifically parse token<hex> adjacency without whitespace separating them, eat all whitespace within a hex value, and return a partially constructed CMap instead of throwing an exception.
> I don't see a problem with the previous test case example (BlackHat...) but I've modified the test case based on an example from the wild: http://www.itsix.com/media/experienced_java_developer.pdf
> edit: forgot to mention that this patch was designed on 1.8.3, but also worked on trunk.
