c# - Special characters in SharpPDF -

I am using the fast PDF DLL () to create PDFs in C #. Everything works great but I can not find any special characters (in fact these are Polish letters such as "a ??, Ä ??, Å ??, a ?? ...") in my output. I'm saving the wire.

Is there any way to do this work?

Thank you. Unfortunately, there are many problems with special characters in the SharpPDF
