title: \xef\xbb\xbf comes in utf8 files java
body: <p>I want to upload a UTF-8 file, while I create utf8 file in windows environment automatically adds
  \xef\xbb\xbf this BOM in starting of the file.Problem is my file starting must be SOF because mapping tool will check this SOF.If I create normal ANSCII file it works ,When I save that file as UTF-8 it brings that unwanted BOM.Help me to create UTF-8 file without this BOM.</p>
