title: Tesseract user-patterns
body: <p>Any one know how to use the user patterns (<code>user_patterns_suffix</code>) in Tesseract? 
  Could you advise me how to do with it and how to test it working? I tried to follow Tesseract guide (<a href="https://github.com/tesseract-ocr/tesseract/blob/master/doc/tesseract.1.asc#config-files-and-augmenting-with-user-data" rel="nofollow noreferrer">Tesseract user-patterns</a> but I didn't see it affected the result at all.</p>
  
  <p>Thanks.</p>
