You can unpack the deu.traineddata file, modify the extracted deu.unicharambigs such that it would always replace the misrecognized characters with § symbol, and then re-combine the component files. Check the Training Wiki for details on the commands.

There are available tools that automated the entire training process. https://github.com/tesseract-ocr/tesseract/wiki/AddOns <https://www.google.com/url?q=https%3A%2F%2Fgithub.com%2Ftesseract-ocr%2Ftesseract%2Fwiki%2FAddOns&sa=D&sntz=1&usg=AFQjCNFOh4_TQG4yDtDEvq5SvZpylpsS_g> On Thursday, June 16, 2016 at 9:01:49 AM UTC-5, [email protected] wrote: > > Hi all, > > I'm trying to set up tesseract to scan German documents.
