title: How to use other language with tesseract on C# Tesseract 3.02 + Emgu 2.4.9
body: <p>My 'tessdate' contain:
  eng.traineddata, eng.cube.bigrams, eng.cube.fold, eng.cube.lm, eng.cube.nn, eng.cube.params
  eng.cube.size, eng.cube.word-freq, eng.tesseract_cube.nn</p>
  
  <p>rus.traineddata, rus.cube.fold, rus.cube.lm, rus.cube.nn, rus.cube.params, rus.cube.size, rus.cube.word-freq</p>
  
  <p>I haven't got 'rus.cube.bigrams' and 'rus.tesseract_cube.nn' files in the tessdata dirrectory.</p>
  
  <p>I fetch this mistake "Unable to create ocr model using Path 'tessdata' and language 'rus'", when I change 'eng' to 'rus' or 'ita' for example in this code:</p>
  
  <blockquote>
    <p>private Tesseract _ocr;</p>
  
  <pre><code>  public LicensePlateDetector(String dataPath)
    {
       //create OCR engine
        _ocr = new Tesseract("tessdata", "rus", Tesseract.OcrEngineMode.OEM_CUBE_ONLY);
       _ocr.SetVariable("tessedit_char_whitelist", "ABCDEFGHIJKLMNOPQRSTUVWXYZ-1234567890");
    }
  </code></pre>
  </blockquote>
  
  <p>Where Am I mistaking?  </p>
