Hello @deaddogs2013! I'm Dosu, a bot here to help you with bugs, answer your questions, and assist you in becoming a contributor. I'm ready to help you while we wait for a human maintainer. How can I assist you today?

I found a similar open issue regarding OCR errors in Stirling-PDF. The suggested solution is to ensure that the eng.traineddata file is the correct size, which should be 23,466,654 bytes, if it was downloaded manually ^[1].

To continue talking to Dosu, mention @dosu.
