Andreas Lehmkühler commented on PDFBOX-5713:
--------------------------------------------
[~tilman] my bad, I just had a look at the title of the document and didn't
look at the details. However, I guess I've found something else
[^5040.Download_Fonts.pdf] chapter 3.3 describes the format and it looks like
the whole header thing in our parser is wrong
> PfbParser fails to parse PFB font with multiple binary records.

> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 3.0.0 PDFBox
> Reporter: Jaromír Dobrý
> Priority: Major
> Attachments: 5040.Download_Fonts.pdf, DejaVuSerifCondensed.pfb,

> * The attached PFB font can be opened in FontForge but PfbParser in fontbox
> fails to read it.
> * The problem is that fontbox assumes there are three records (ascii,
> binary, ascii) in the PFB file but the binary part is split into multiple
> shorter chunks (i.e. ascii, binary, ..., binary, ascii).
> * I didn't find that this is forbidden and according to FontForge behavior
> it seems to be valid.
> * The fix seems to be easy, it is probably sufficient to concatenate the
> binary records together in PfbParser and the result will work correctly.
