C#-NReco.PdfGenerator非英语字符未呈现

我正在使用NReco.PdfGenerator库从html生成pdf。对于英语来说，这很好。我还要求包括非英语语言（马拉地语），在这种情况下不能像预期的那样工作。渲染黑盒

这是我的行动方法：

public ActionResult Assesment_DownloadResultSummaryData(string htmlContent){
  var htmlToPdf = new HtmlToPdfConverter();
                    var margins = new PageMargins();
                    margins.Bottom = 10; // margins.Left = 5;margins.Right = 5;
                    margins.Top = 10;
                    htmlToPdf.Margins = margins;
                    htmlToPdf.CustomWkHtmlPageArgs = "--enable-smart-shrinking  --encoding <encoding>";
                    htmlToPdf.PageFooterHtml = $@"page <span class=""page""></span> of <span class=""topage""></span><br />";
                    //htmlToPdf.Orientation = NReco.PdfGenerator.PageOrientation.Portrait;
                    htmlToPdf.Zoom = 1.0f;
                    return File(htmlToPdf.GeneratePdf(htmlContent, null), "application/pdf","myFile.pdf");

}

这对我也不起作用。 我的html包含如下字符विषय,मूल्यांकन प्रकार 这在我的pdf中，它显示为​लà¥​掴掴掴掴掴掴掴掴掴掴掴掴

htmlContent的某些部分：

                    <td  colspan="6"><p><b>मुल्यांकन निकाल</b></p></td>

我找到了一个解决这个问题的办法，用NReco代替

一些示例代码：

   <tbody><tr>
                    <td  colspan="6"><p><b>मुल्यांकन निकाल</b></p></td>
            </tr>
            <tr>

                <td style="width:5%"><h4><b>वर्ग :</b></h4></td>
                <td style="width:10%;text-align:left;"><h4><b>Class 1-A</b></h4></td>
                <td style="width:10%"><h4><b>बॅच :</b></h4></td>
                <td style="width:40%;text-align:left;"><h4><b> 25-07-2017-Class 1-A-General Knowledge-English-1</b></h4></td>
                <td style="width:20%"><h4><b>विद्यार्थ्यांची एकूण संख्या :</b></h4></td>
                <td style="width:10%"><h4><b>18</b></h4></td>
            </tr>
            <tr >

                <td style="width:10%;text-align:left;"><h4><b>English</b></h4></td>
                <td style="width:10%"><h4><b>विषय :</b></h4></td>

                <td style="width:10%"><h4><b>17</b></h4></td>
            </tr>

        </tbody>

public ActionResult ConverToPdf(string htmlContent)
        {
            try

                HtmlToPdf converter = new HtmlToPdf();

                int webPageWidth = 1024;
                // set converter options
                converter.Options.PdfPageSize = pageSize;
                converter.Options.PdfPageOrientation = pdfOrientation;
                converter.Options.WebPageWidth = webPageWidth;
                converter.Options.MarginLeft = 10;
                converter.Options.MarginRight = 10;
                converter.Options.MarginTop = 5;
                converter.Options.MarginBottom = 5;
                //converter.Options.WebPageHeight = webPageHeight;

}

该命令对我有效。

您在pdf中使用的字体是否确实包含您试图放入pdf中的tekst的字形？视图中的显示正确。如果没有“htmlContent”变量的值，很难说出具体的内容。wkhtmltopdf可能会回退到不包含马拉地字符的字体。是否有任何方法包含这些字符。
