Juraj Lonc updated PDFBOX-1473:
-------------------------------
Attachment: parsingfix_Type2CharStringParser.patch
parsingfix_CFFFont.patch
I made fix in parser.
"callsubr" and "callgsubr" commands are processed directly in parser so parser
works with correct count of stems.
Parser works OK with this modification and CharString is being decoded
correctly.
But I found another bug. OpenType fonts may have CMAP definition (like the one
in attached PDF). And this CMAP is not handled/processed. You are expecting
that Type1 font cannot have CMAP. This causes that no character is
printed/drawed despite font is parsed correctly (now).
