OK, it looks like podofotxtextract expects to be able to instantiate a
PdfFont from the embedded font. In the case of "chinese.pdf" there is no
font embedded; the fonts are instead replaced by Acrobat.
I'll have a look and see what can be done about this. I'm not really
much good with the contents and fonts side of PDF, though.

OK. The problem is that PdfFontFactory.cpp:163 calls:
pFont = new PdfFontCID( pMetrics, NULL, pObject, false );
which tries to construct a PdfFontCID without a PdfEncoding, resulting
in a crash at /home/craig/build/podofo/src/PdfFontCID.cpp:78 in
PdfFontCID::Init :
m_pEncoding->AddToDictionary( m_pObject->GetDictionary() );
^^^^^^^^^^^
is null
I don't know enough about PDF fonts to know what to do about this at
present, and my fever has come back up so I need to go back to bed. Ideas?
