Html Div with tags and Hindi Unicode to PDF in asp net c

Question

In ASP.NET using C#, I want to export HTML div> with content in Hindi (Unicode characters) to PDF. I've used a variety of third-party HTML to PDF conversion programmes, including nReco, evopdf, hiqpdf, and others. None of them are functioning properly, in the sense that the Hindi text is either not displayed or is not rendered appropriately. For example, if I have the Unicode text ""न्‍यायालय,विरूद्व,डब्‍ल्‍यु"" the characters are represented improperly.
