HTML To PDF Turkish Character Problem - pdf

Question

I want to convert a ASP.NET web page to pdf using ITextSharp. I did write some code but I can not make it show the Turkish Characters. Can anyone help me?
Here is the code:
using System;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Web.UI;
using System.Web;
using iTextSharp.text.html.simpleparser;
using System.Text;
using System.Text.RegularExpressions;
namespace Presentation
{
public partial class TemporaryStudentFormPrinter : System.Web.UI.Page
{
protected override void Render(HtmlTextWriter writer)
{
MemoryStream mem = new MemoryStream();
StreamWriter twr = new StreamWriter(mem);
HtmlTextWriter myWriter = new HtmlTextWriter(twr);
base.Render(myWriter);
myWriter.Flush();
myWriter.Dispose();
StreamReader strmRdr = new StreamReader(mem);
strmRdr.BaseStream.Position = 0;
string pageContent = strmRdr.ReadToEnd();
strmRdr.Dispose();
mem.Dispose();
writer.Write(pageContent);
CreatePDFDocument(pageContent);
}
public void CreatePDFDocument(string strHtml)
{
string strFileName = HttpContext.Current.Server.MapPath("test.pdf");
Document document = new Document(PageSize.A4, 80, 50, 30, 65);
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
StringReader se = new StringReader(strHtml);
HTMLWorker obj = new HTMLWorker(document);
document.Open();
obj.Parse(se);
document.Close();
ShowPdf(strFileName);
}
public void ShowPdf(string strFileName)
{
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "inline;filename=" + strFileName);
Response.ContentType = "application/pdf";
Response.WriteFile(strFileName);
Response.Flush();
Response.Clear();
}
protected void Page_Load(object sender, EventArgs e)
{
}
}
}

Answer 1

iTextSharp.text.pdf.BaseFont STF_Helvetica_Turkish = iTextSharp.text.pdf.BaseFont.CreateFont("Helvetica", "CP1254", iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font fontNormal = new iTextSharp.text.Font(STF_Helvetica_Turkish, 12, iTextSharp.text.Font.NORMAL);
You should pass the font as an argument in itextsharp manipulation commands like that :
pdftable.AddCell(new Phrase(nn.InnerText.Trim(), fontNormal));
You might want to consider working with reporting tools with pdf exporting capability instead of direclty working with pdf which can be a real headache..

You'll need to make sure you are writing the text in a Font that supports the Turkish character set (or at least the caracters you are trying to write out).
I don't know what HtmlTextWriter does in terms of font use - it will presumably use one of the standard built-in fonts that are unlikely to support the characters you want to print if the fall outside of the Latin1 or Latin1-extended Unicode ranges.
I use BaseFont.createFont(...) to have an external Font included in my PDF in iText (Java) - one which supports all the characters that I am writing. You might be able to create your Font object and then pass it to HtmlTextWriter?

PdfFont font = PdfFontFactory.CreateFont("Helvetica", "CP1254",PdfFontFactory.EmbeddingStrategy.FORCE_NOT_EMBEDDED);
doc.Add(new Paragraph("P").SetFont(font));
