John Hewson commented on PDFBOX-2599:
-------------------------------------
Ok, I've solved the main problem with 2.0. The file has a number of errors, the
fonts use Identity-H encoding but are not embedded, the CID2GIDMap is missing,
we expect to fallback to the ToUnicodeMap, but that is missing too. Broken
fonts like these fall under an ambiguous part of the PDF spec:
{quote}
The conforming reader shall select glyphs by translating characters from the
encoding specified by the predefined CMap to one of the encodings in the
TrueType font's 'cmap' table. The means by which this is accomplished are
implementation-dependent.
{quote}
We try to emulate Acrobat's undocumented behaviour as much as possible, in the
case it's not working as we were expecting a ToUnicodeMap to fall back to. The
fix is to check if the ToUnicodeMap is missing, and if so, fall back to using
an Identity encoding.
