title: OCR with Unity3d
body: <p>I would like to implement a letter detection feature for my "guess the drawing" game in Unity, that would detect if someone draws a letter and I would count it as cheating. So people would only be able to draw the word requested as pictures and would not draw the letters that create word itself.</p>
  
  <p>I would like to know what is your opinion and what technology can I use for this task in Unity3d. Thanks in advance.</p>
