Arabic Text in PdfBox

Question

Hi I was trying to display Arabic text in the pdf using pdfbox, but unfortunately I'm unable to get the proper output which was required. I was getting in reverse instead of reading right to left it is reading left to right. Can anyone help me how to read right to left using pdfbox, as I'm new to pdf box.
