this what i used to do to remove such weird characters

  • go to vim
  • then go to that particular character press "ga" ( will show you hex / octal values )
  • close the file.
  • perl -pi -e 's/\x(hex value)//g' <filename>

this may not be the best way to do what you wanted but it works for me.
