c# – Html to pdf一些字符丢失(itextsharp)

概述我想通过使用itextsharp库将gridview导出为pdf.问题是在pdf文档中缺少一些土耳其字符,如İ,ı,Ş,ş等.用于导出pdf的代码是： protected void LinkButtonPdf_Click(object sender, EventArgs e) { Response.ContentType = "application/pdf"; 我想通过使用itextsharp库将grIDvIEw导出为pdf.问题是在pdf文档中缺少一些土耳其字符,如İ,ı,Ş,ş等.用于导出pdf的代码是：

protected voID linkbuttonpdf_Click(object sender,EventArgs e)    {        Response.ContentType = "application/pdf";        Response.ContentEnCoding = System.Text.EnCoding.UTF8;        response.addheader("content-disposition","attachment;filename=filename.pdf");        Response.Cache.SetCacheability(httpCacheability.NoCache);        System.IO.StringWriter stringWrite = new StringWriter();        System.Web.UI.HTMLTextWriter HTMLWrite = new HTMLTextWriter(stringWrite);        GrIDVIEw1.RenderControl(HTMLWrite);        StringReader reader = new StringReader(textConvert(stringWrite.ToString()));        document doc = new document(PageSize.A4);        HTMLWorker parser = new HTMLWorker(doc);        pdfWriter.GetInstance(doc,Response.OutputStream);        doc.open();        parser.Parse(reader);        doc.Close();    }    public static string textConvert(string S)    {        if (S == null) { return null; }        try        {            System.Text.EnCoding encFrom = System.Text.EnCoding.UTF8;            System.Text.EnCoding encTo = System.Text.EnCoding.UTF8;            string str = S;            Byte[] b = encFrom.GetBytes(str);            return encTo.GetString(b);        }        catch { return null; }    }

注意：当我想在pdf文档中插入字符时,会显示缺少的字符.我用这段代码插入字符：

BaseFont bfFont = BaseFont.CreateFont("C:\windows\Fonts\arial.ttf",BaseFont.IDENTITY_H,BaseFont.NOT_EMbedDED);        Font Fontozel = new Font(bfFont,12,Font.norMAL,new color(0,0));        doc.Add(new Paragraph("İİııŞŞşşĞĞğğ",Fontozel));

解决方法 最后我想我找到了解决方案,我改变了它的一些源代码,以显示土耳其字符(土耳其语字符代码是cp1254)

I add “public const string CP1254 = "Cp1254";” to [BaseFont.cs] in the source code.

After that I modify the [FactoryPropertIEs.cs].I changed like this;

public Font GetFont(ChainedPropertIEs props){I don't write the whole code.I changed only code below;------------Default itextsharp code------------------------------------------------------  if (enCoding == null)                enCoding = BaseFont.WINANSI;            return FontImp.GetFont(face,enCoding,true,size,style,color);-------------modifIEd code--------------------------------------------            enCoding = BaseFont.CP1254;            return FontImp.GetFont("C:\windows\Fonts\arial.ttf",color);}

在编译新的dll之后,显示缺少的字符.
