[jira] Created: (PDFBOX-619) Reapplying parts of PDFBOX-542

Reapplying parts of PDFBOX-542
------------------------------

                 Key: PDFBOX-619
                 URL: https://issues.apache.org/jira/browse/PDFBOX-619
             Project: PDFBox
          Issue Type: Bug
          Components: FontBox
    Affects Versions: 1.0.1
            Reporter: Villu Ruusmann
         Attachments: FontBox.patch

The application of PDFBOX-542 was accompanied with several optimizations. Later testing has revealed that one of the optimizations - the replacement of List-type field org.apache.fontbox.cff.encoding.CFFEncoding#entries with two Map-type fields #code2sid and #sid2code - may come short in situations where the mapping between codes and SIDs is not one-to-one (AFAIK, it is not covered by the CFF specification, but there are real-life examples for that).

I've compiled a patch file that restores the code in the original state.

----------------------------------

    Attachment: FontBox.patch

When testing with finer logging level (debug instead on info), it turned out that class org.apache.pdfbox.pdmodel.font.PDType1CFont was still complaining about not being able to handle some codes. Closer inspection revealed that all the problematic codes were encoded as supplements.

I have enhanced the patch file to extract mapping information also from supplements.
