Exporting Special Characters

This article demonstrates how you can use custom fonts to export non-ASCII characters to PDF.

If you do not specify a font explicitly any non-ASCII characters the exported DOM element contains will not be exported to the PDF file.

Example: Consider the following <div> element, which contains Swedish and Japanese characters(Kanji):

<div id="foo">Västergötland(West Gothia) 日本(Japan)</div>
#foo {
    background-color: grey;
    color: white;

This is how it looks like in the browser:

Special Characters

Exporting this <div> to PDF would result in the following:

Special Characters Missing

The special characters are missing in the exported file, because the standard fonts used in exporting to PDF do not support non-ASCII characters. In order to export them you have to use a custom font that supports them. The custom font file has to be included in the project and the font has to be added to the RadClientExportManager's PdfSettings.Fonts collection and set to the element you want to export (in this example the <div> "foo").

  • We will include the Arial Unicode MS font in our project's "Fonts" folder and add it to the PdfSettings.Fonts collection. It is an extended version of the Arial font and supports Unicode characters.
protected void Page_Load(object sender, EventArgs e)
    RadClientExportManager1.PdfSettings.Fonts.Add("Arial Unicode MS", "Fonts/ArialUnicodeMS.ttf");
Protected Sub Page_Load(sender As Object, e As EventArgs)
    RadClientExportManager1.PdfSettings.Fonts.Add("Arial Unicode MS", "ArialUnicodeMS.ttf")
End Sub
  • Apply the font to the <div> "foo":
#foo {
    font-family: 'Arial Unicode MS';
    background-color: grey;
    color: white;
  • Export the <div>:
<telerik:RadClientExportManager runat="server" ID="RadClientExportManager1">
    <pdfsettings filename="Myfile.pdf" />
<input type="button" onclick="exportElement()" value="export" />

<script type="text/javascript">
    function exportElement() {
        var exp = $find("<%= RadClientExportManager1.ClientID %>");

The special characters are correctly exported and visible in the PDF file:
