Most commercial OCR engines will return word and character coordinate positions but you have to work with their SDK’s to extract the information. Even Tesseract OCR will return position information but it has been not easy to get to. Version 3.01 will make easier but a DLL interface is still being worked on.
Unfortunately, most free OCR programs use Tesseract OCR in its basic form and they only report the raw ASCII results.

www.rerecognition.com – KADMOS engine returns coordinates.
