title: Tesseract fails to scan when text is aligned center
body: <p>It works fine if the text is aligned to th left like this</p>
  
  <p>Bộ phim “Chúa tế Godzilla: Đế vương bất tứ" do ai đạo diễn?</p>
  
  <p>Dan Harris</p>
  
  <p>Simon Kinberg</p>
  
  <p>Michael Dougherty</p>
  
  <p>but when the question is aligned to center like this:</p>
  
  <p>Bộ phim “Chúa tế Godzilla: Đế vương bất tứ" </p>
  
  <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;do ai đạo diễn?</p>
  
  <p>Dan Harris</p>
  
  <p>Simon Kinberg</p>
  
  <p>Michael Dougherty</p>

  <p>In this case, sometimes tesseract gives me some nonsense words, sometimes it cannot scan anything at all. And here is the code I use:</p>
  
  <pre><code>image = cv2.imread(args["image"])
  gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
  gray = cv2.resize(gray, None, fx=2, fy=2, interpolation=cv2.INTER_CUBIC)
  
  if args["preprocess"] == "thresh":
             gray = cv2.threshold(gray, 0, 255,
                          cv2.THRESH_BINARY | cv2.THRESH_OTSU)[1]
  
  elif args["preprocess"] == "blur":
                  gray = cv2.medianBlur(gray, 3)
  filename = "Screens/{}.png".format(os.getpid())            
  
  cv2.imwrite(filename, gray)
  text = pytesseract.image_to_string(Image.open(filename), lang='vie')
  </code></pre>
  
  <p>Please tell me how can I solve this problem? I want Tesseract to work fine with any situation.</p>
