I have found a solution to use tagged pdf font informations on orginal PDF file
But I have still doubts on how 'tagging' can fix TrueType font encoding.
- TrueType font should have a cmap table, is there a way to verify/extract it using SDK or opening the PDF?
- If a TrueType Font program is embedded in PDF, how this should work? If copy and paste of text doesn't work, this means the the font program is wrong or missing?
Thanks
