I obtained the document from a 3rd party, so I am not sure, but looking 
at the "producer" field in it's meta data I see 'Adobe Acrobat Pro 
11.0.6 Paper Capture Plug-in'. So it appears, you are correct, the 
document might have been scanned. Ouch!

What are my options for extracting an error-free text? Using a better 
OCR software?  I have just started using pdfbox, so I haven't compiled 
any statistics on the variety or frequency of these errors,  How do 
people deal with this issue? Is it possible to write a set of rules for 
a few characters?

Thank you,
