问题 Is there the way to create iTextSharp font using additional info (such as gdiCharSet etc) from System.Drawing.Font object? 回答1: Short answer: Yes. Long answer: Each attribute is a bit different, but all that information can be expressed within PDF in general, and iText[Sharp] in specific. You can specify a font's encoding when you create it, but you must do so in a way iText understands. Specifically, encoding values are strings within iText[Sharp]. BaseFont has a number of public static
