Text extraction will only work if everything that is necessary to map a glyph (that is the 'drawing' of a character that you see on a PDF page) back to a character is stored in the PDF file. Actually, it is very likely not a lack of font embedding, this problem is usually caused by documents that do not contain all the information that Acrobat needs to extract text.Ĭonverting a PDF file to any other format is one of the most complex things you can do with a PDF file.
