>
> The enconding of a PDSimpleFont is determined in determineEncoding. It
> contains a series of ifs. Most notably at the end there is a:
> if (encoding instanceof COSDictionary) { ... }
> else if (encoding instanceof COSStream) { ... }
> This is wrong because COSStream is a subclass of COSDictionary, so the
> program will never get into the COSStream-specific block, which is
> responsible for the parsing of embedded CMAPs. The solution would be to
> reverse the order of those ifs.
