    Double Underline of font family "Calibri" doesn't look match after exporting to PDF

    Steps to get this issue.

    A. Insert double underline (═══)  in the rich text box. ( RichTextBox.Commands.InsertTextCommand.Execute(\u2550); )

    B. Change the font to "Calibri" and font size to 10. 

    C.Export into pdf using PdfFormatProvider.Export

    You could see the double underline in PDF looks longer that what we see in the rich text box. 

    If the double underline (═══)  is set to "Times New Roman"it matches the PDF export

     Is it some thing to do with the font family ?

    Hello Anand,

    As this symbol is not available in "Calibri" font, RadRichTextBox fallback mechanism finds another font that contains it. In this concrete case the fallback font is "Microsoft YaHei". I have also tested how MS Word exports the same case and it also fallbacks to another font - in their case this is "Arial". As RadRichTextBox UI draws the text using WPF TextBlocks I suppose that this control also uses different fallback font for rendering the glyph, which explains the difference between the UI and PDF export.

    I hope this is helpful. If you have other questions please contact us again.
