Kendo Grid pdf export problem in persian/arabic language

I am using the built in functionality of KendoUi Grid to export the grid data in pdf http://demos.telerik.com/kendo-ui/grid/pdf-export. It is working properly when data language is English. But when data language is right to left such as persian or arabic, in pdf export show letters separately and contrariwise. for example show "م‌ا‌ن" instead of "نام". How can Solve it. My Code:

@(Html.Kendo().Grid<MyModel>()
    .Name("GridName")
    .ToolBar(toolbar =>
    {
        toolbar.Pdf().Text(" ").HtmlAttributes(new { @class = "excel-pdf-btn fa fa-file-pdf" });
    })
    .Pdf(pdf => pdf.AllPages().FileName("MyFileName.pdf").PaperSize("A4").ProxyURL(Url.Action("Pdf_Export_Save", "Grid")))
    .Columns(columns =>
    {
        columns.Bound(t=> t.Id).Visible(false);
        columns.Bound(t => t.Name).Title("نام");
    .DataSource(t => t
        .Ajax()
        .Model(m => m.Id(i => i.Id))
        .PageSize(15)
        .Read(r => r.Action("FillGrid", "MyController"))
    )
)

Update: I embed ttf font. but problem not solved.

<script>
    kendo.pdf.defineFont({
        'serif': 'MyFont',
        'serif|bold': 'MyFont',
        'serif|italic': 'MyFont',
        'serif|bold|italic': 'MyFont',
        'sans-serif': 'MyFont',
        'sans-serif|bold': 'MyFont',
        'sans-serif|italic': 'MyFont',
        'sans-serif|bold|italic': 'MyFont',
        'monospace': 'MyFont',
        'monospace|bold': 'MyFont',
        'monospace|italic': 'MyFont',
        'monospace|bold|italic': 'MyFont',   
        "MyFont" : "@Url.Content("~/Content/fonts/MyFont.ttf")"
    });
    </script>
