    For Turkish encoding

    CultureInfo ci = new CultureInfo("tr-TR");
Encoding enc = Encoding.GetEncoding(ci.TextInfo.ANSICodePage);

    If you're outputting HTML, try different DOCTYPE tags at the top of the page.

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

    Note if using HTML you may need to HTMLEncode the characters.

    Server.HTMLEncode()

    HttpServerUtility.HtmlEncode()

    I strongly suggest not to change itextsharp source code in order to solve this problem. Have a look at my other comment on the subject: https://stackoverflow.com/a/24587745/1138663

    I solved the problem. I can provide my the other solution type...

    try
{
        BaseFont bf = BaseFont.CreateFont("c:\\windows\\fonts\\calibrib.ttf",
            BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
        Document document = new Document(PageSize.A4, 25, 25, 30, 30);
        PdfWriter writer = PdfWriter.GetInstance(document, fs);

        Font f = new Font(bf, 12f, Font.NORMAL);
        // Open the document to enable you to write to the document
        document.Open();
        // Add a simple and wellknown phrase to the document
        for (int x = 0; x != 100; x++)
        {
            document.Add(new Paragraph("Paragraph - This is a test! ÇçĞğİıÖöŞşÜü",f));
        }

        // Close the document
        document.Close();          
}
catch(Exception)
{

}

    I am not familiar with the iTextSharp library; however, you seem to be converting the output of your gridview component to a string and reading from that string to construct your PDF document. You also have a strange conversion from UTF-8 to UTF-8 going on.

    From what I can see (given that your GridView is outputting characters correctly) if you are outputting the characters to a string they would be represented as UTF-16 in memory. You probably need to pass this string directly into the PDF library (like how you pass the raw UTF-16 .NET string "İııŞŞşşĞĞğğ" as it is).

    BaseFont bF = BaseFont.CreateFont("c:\\arial.ttf","windows-1254",true);
Font f = new Font(bF,12f,Font.NORMAL);
Chunk c = new Chunk();
c.Font = f;
c.Append("Turkish characters: ĞÜŞİÖÇ ğüşıöç");
document.Add(c);

    In the first line, you may write these instead of "windows-1254". All works:

    • Cp1254
    • iso-8859-9
    • windows-1254
