Hi, The relevant code, where PdfFontCID ist called with a NULL PdfEncoding is only called, when you try to construct a PdfFont from an existing object in a PDF file. Support for this is not very good. It works with simple fonts, but PoDoFo is currently not able to consturct the encoding for a CID font from a PDF file. So, PoDoFo should not crash in this case, but maybe throw an exception that this is not supported.
What do you want to do excactly? Maybe we can find another solution.
Best regards,
Dominik
