OCR software is made for the purpose of creating the fonts table as the means by which searchable text is created or any other form of text is created for export to another application.

Do you have a source for that? I've been searching and can't find any discussion of OCR putting a font table into a PDF. I'm not sure why it would be necessary, since plain ASCII text with no formatting is adequate for making a searchable PDF (which is what OCR is for). And none of the OCR I've done with the intention of exporting the text to another application ever bothered trying to specify or render the font.

You misunderstood the meaning. The PDF contains a font table. When an OCR application supplies text without a Postscript type of designation for a font, the PDF software generates fonts for the text in accordance to the Postscript like instructions provided by the OCR software. Adobe Acrobat uses the Adobe Multiple Masters fonts to generate the font table for the PDF file. The absence of a fonts table in the PDF file tends to signify the Postscript like instructions for constructing such a font table were not received from the source scan. Since OCR software always creates a text layer, it appears the absence of fonts in the PDF font table indicates there was no OCR text layer and no OCR software to produce the extended ASCII, Unicode, and/or Postscript like instructions for the PDF fonts table.
