title: Character confidence for Tesseract 3.02 using config file
body: <p>How would I get the % confidence per character detected?
  By searching around I found that you should set save_blob_choices to T.
  So I added that to as a line in the hocr config file in tessdata/configs and called tesseract with it.
  This is all I'm getting in the generated html file:</p>
  
  <pre><code>&lt;span class='ocr_line' id='line_1' title="bbox 0 0 50 17"&gt;&lt;span class='ocrx_word' id='word_1' title="bbox 3 2 45 15"&gt;&lt;strong&gt;31,835&lt;/strong&gt;&lt;/span&gt;
  </code></pre>
  
  <p>As you can see there isn't any confidence annotations not even per word.</p>
  
  <p>I don't have visual studio so I'm not able to make any code changes. But I'm also open to answers describing code changes as well as how I would compile the code without VS.</p>
