Michael Klink commented on PDFBOX-5023:
---------------------------------------
In particular text extraction as described in the PDF specification does not
rely on specific font program tables. Of course one could go further than that
algorithm but the first one to address if the algorithm from the specification
does not work is the PDF producer...
And indeed, for any sensible further analysis of this topic an example PDF plus
a pointer towards where text extraction failed with that PDF should be provided.
