title: Why does pytesseract fail to recognize digits in this simple image?
body: <p>I'm trying to use pytesseract to recognize two numbers from an image:</p>
  
  <p><a href="https://i.stack.imgur.com/oAAXR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oAAXR.png" alt="enter image description here"></a></p>
  
  <ul>
  <li>I have tried <code>--psm 6</code> up to <code>10</code></li>
  <li>I have tried <code>-c tessedit_char_whitelist=0123456789'</code></li>
  </ul>
  
  <p>None of the above returns <code>49</code> number. Closest I got is returned <code>4</code> without <code>9</code></p>
  
  <p>Do you have any tips about how to make tesseract recognize it ?</p>
