Thanks for the replay, If you mean if i have the latin and common unicharset in the tessdata direcotry( /usr/share/tesseract-ocr/tessdata ),i have downloaded them and placed them in the directory and still getting the same behavior. I have also tried doing it from my windows machine which has 3.05 version, and had same behavior .
