"Invalid type of toUnicode CMap encountered" calling GetPages()

RaduPoenaru commented 1 year ago

I'm using PdfPig to (magically) parse an auto-generated PDF. It worked until a few weeks ago, when new PDFs have started throwing this error.

It is an exact duplicate of issue #354. As far as my limited understanding of PDFs goes:

The ToUnicode token of the font points to a reference (26?) that is indeed missing from the cross reference stream.
Objects 26 and 32 are missing from the table, a result confirmed by any PDF reader/analyzer.
Using some PDF analyzer the table does seem to be messed (see attached image?) but every other app opens the PDF just fine, so what can I do now?

I cannot upload the PDFs publicly, but I could email a de-personalized version of it

@RaduPoenaru the pre-release package published last night may have a fix for this, can you try it out and let us know please?

Closing but feel free to reopen if the issue persists
