I made a single modification in the source code provided for the silverPDF "Unicode" sample project.
XFont font = new XFont("Times New Roman", 12, XFontStyle.Regular, options);
XFont font = new XFont("Times New Roman", 12, XFontStyle.Bold, options);
The result of this change is not a bold font (I opened the created PDF file with Adobe Reader 9.0).
The only difference is a bigger spacing between characters (compared to PDF created with original sample code).
Is this a known issue ? or is it a bug ?
Is there something else I need to do in order to enable bold for unicode fonts ?
