iTextSharp (export to pdf)

Can you help me with my Turkish character (İışŞğĞ) problem? I could not complete my project. Can you write the sample code and where to add the code? Thank you so much.

Please explain in details what error you got.

Turkish characters are lost on export to PDF. I need a code where I can add Turkish characters (İışŞĞ) to iTextSharp. In which line do I add these codes?

ASP.NET Make uses iTextSharp.LGPLv2.Core which is based on iTextSharp v4.1.6. Read its FAQ on how to use unicode font below:
