Don't use Weka, since you are already using NetBeans, it's better if you change NetBeans configuration to UTF-8

  1. Open etc folder inside the Netbeans directory (path where you installed NetBeans). Edit netbeans.conf using Notepad or any text editor.

  2. Look for this field: netbeans_default_options add If it is already present, change it to
    -J-Dfile.encoding=UTF-8

  3. Else, add a new line at the end of the file:

    netbeans_default_options="-J-Dfile.encoding=UTF-8"
  4. Restart Netbeans.
