string data using iTextSharp.tepdf data convertion kannada font issue

To handle Kannada font conversion in iTextSharp for PDF generation, you need to ensure that the font used for rendering Kannada characters is available and properly embedded in the PDF. Here's a step-by-step guide to achieve this:

1. Download the Kannada font: First, you need to download the appropriate Kannada font that you want to use in your PDF. Ensure that the font supports Unicode and includes all the required characters.

2. Add the font to your project: Once you have the Kannada font file, add it to your project's font folder or any other suitable location.

3. Use the font in iTextSharp: Now, you need to create a custom font object using the Kannada font file and register it with iTextSharp. You can do this using the BaseFont.CreateFont method. Make sure to set the encoding as BaseFont.IDENTITY_H to handle Unicode characters.

Here's an example of how you can modify your code to include the Kannada font:

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;

// Load the Kannada font file
BaseFont kannadaFont = BaseFont.CreateFont("path/to/kannada_font.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

StringReader sr = new StringReader(sb.ToString());
byte[] bytes = null;

using (MemoryStream memoryStream = new MemoryStream())
{
    iTextSharp.text.Document pdfDoc = new iTextSharp.text.Document(PageSize.A4, 10f, 10f, 10f, 0f);
    PdfWriter writer = PdfWriter.GetInstance(pdfDoc, memoryStream);

    pdfDoc.Open();

    // Create a custom font with the Kannada font
    Font kannadaCustomFont = new Font(kannadaFont, 12);

    // Create a Paragraph with the Kannada font
    Paragraph paragraph = new Paragraph("Your Kannada text here", kannadaCustomFont);

    // Add the Paragraph to the PDF document
    pdfDoc.Add(paragraph);

    pdfDoc.Close();

    bytes = memoryStream.ToArray();
    Session["pdfbeforeesign"] = bytes;
    memoryStream.Close();
}

Replace "path/to/kannada_font.ttf" with the actual path to your Kannada font file.
