How to use Chinese fonts？

[HmgsLJ]

First thanks to the author for providing a good library, but I had a problem with version 6.0, that is, using Chinese fonts will make an error, what can I do to solve it.

Error：

System.InvalidOperationException:“No appropriate font found for family name '宋体'. Implement IFontResolver and assign to 'GlobalFontSettings.FontResolver' to use fonts.”

Code：

           // 创建一个新的PDF文档
           using (PdfDocument document = new PdfDocument())
           {
               // 添加一页
               PdfPage page = document.AddPage();
               XGraphics gfx = XGraphics.FromPdfPage(page);
               // 加载字体
               //XFont font = new XFont("simsun.ttc", 12, XFontStyleEx.Regular);
               XFont font = new XFont("宋体", 12, XFontStyleEx.Regular);

               // 绘制中文文本
               gfx.DrawString("你好，世界！", font, XBrushes.Black, new XRect(50, 50, page.Width, page.Height), XStringFormats.TopLeft);

               // 保存PDF文档
               string outputPath = "D://output.pdf";
               document.Save(outputPath);
           }

The answer to your question is in the error message: Implement IFontResolver or use either the GDI or WPF build.

问题的答案在错误消息中：实现或使用 GDI 或 WPF 生成。IFontResolver

Yes, I saw it, felt my stupidity, the problem was solved, implementing IFontResolver fixed the problem

No need to feel stupid. This is a breaking change that needs some explanation and we are trying to improve this error message even further.
