Is there such a reader? Is the content organised to make it
possible.
I haven't seen one.
I did start trying to write an heuristic probabilistic OCR one 25 years
ago. The idea being to overlay the OCR'd (displayed with matching fonts)
over the scanned content. Besides visual confirmation and indication of
probability of accuracy with each character, it lends itself well to
hiring neighborhood kids to type in just the "wrong" characters to clean
up the OCR'd file, and heuristically tune the font database, including
adding new fonts - EVERY character is "wrong" until it repeats a few times
in the document. ("clean up" a NYT article, and the OCR now has their
font).
