        column.addElement(new Paragraph("الاسم العائلي      : ", fontAR));                   
     column.go();

Answer 1

Can you try this: String str = new String("الاسم العائلي :".getBytes("ISO-8859-1"),"utf-8"); Then add the string str to your itext paragraph:

column.addElement(new Paragraph(str, fontAR));

Answer 2

Remove the first column.go() because it doesn't make sense:

1. You didn't add any content yet, so there is nothing to render.
2. You didn't define a Rectangle yet, so there will be an error because iText doesn't know where to render this nothing.
