Special characters displayed incorrectly when compression disabled in local ReportViewer RRS feed

  • Question

  • Hi, in my WPF application I am using Microsoft.ReportViewer.WinForms.dll to generate a PDF file on the fly. I don't want the PDF file to be compressed so I set the HumanReadablePDF attribute to true:

    LocalReport localReport = new LocalReport { ReportPath = "Report1.rdlc" };
    Warning[] warnings;
    string[] streamids;
    string mimeType, encoding, extension;
    string deviceInfo = "<DeviceInfo><HumanReadablePDF>True</HumanReadablePDF></DeviceInfo>";
    byte[] data = localReport.Render("PDF", deviceInfo, out mimeType, out encoding, out extension, out 
    streamids, out warnings);
    File.WriteAllBytes("Test.pdf", data);

    My RDLC file contains a textbox containing the euro currency symbol:

    <Textbox Name="Textbox1">
              <Value>Testing €</Value>
              <Style />
          <Style />

    The problem is that the euro symbol is rendered as a question mark.

    Help is appreciated.

  • Can you try escaping the euro character as:

    &euro; or &#8364;

  • No, same result.

  • When I use the report viewer and hit export to pdf I get the euro sign correctly.

    If I open the PDF file in a text editor with the ? and replace it by hand with the euro sign it works also correctly.

  • When you hit the export to pdf menu item the PDF file is compressed by default. In that case the euro sign is rendered correctly. But I don't want the file to be compressed. That's why I set the HumanReadablePDF attribute.

  • I will give a try to SAP Crystal Reports for VS 2013 instead of 2010 and see if this is resolved

  • Crystal Reports are really SAP Crystal Reports and from SAP forum there is an explanation that fits this issue (since the euro sign is non-Western European character) and from what I can tell the PDF is created with ANSI Encoding.

    << /Type /Font /Subtype /Type1 /BaseFont /Helvetica /Encoding /WinAnsiEncoding >>

  • cnk_gr, I really appreciate your response. 

    But I don't have a solution to my problem. 

    It looks like a problem in ReportViewer. Compressed files are rendered correctly. Human readable files are not.

  • It looks like ReportViewer has an issue where the de-compressed output will not display Unicode symbols like the euro. 

    Is there someone having a fix?

  • Trying the same thing with

    VS 2013 (ReportViewer controls version 11) worked like a charm.

    VS 2010 (ReportViewer controls version 10) didn't work.
