title: How to merge new traineddata into eng.traineddata on Tesseract
body: <p>I need to train a new font of English. At the end of training, I have file font.traineddata. How can I merge this into the existing eng.traineddata?</p>
  
  <p>I know that I can use the new traineddata by invoking command
  tesseract input output -l eng+font</p>
  
  <p>But is it possible to merge 2 traineddata?</p>
