alcinnz, LibPoppler's vendored "FoFi" library provides a couple classes to aid parsing binary files (with lookuptables for charsets), & uses themto simplistically parse the major font formats common in PDFs.
I expected LibFreeType to be involved... But all the sophisticated handling of font files is, for worse, precomputed in PDFs prior to saving the file.
