Why cannot support Chinese when convert html to PDF? 支持中文？

Can you tell me how to support Chinese ?

` var htmlStr = "

Support Chinese，支持中文 PDF.

";

PdfDocument pdf = PdfGenerator.GeneratePdf(htmlStr, PageSize.A4);
pdf.save("zh.pdf");
`

Begin with the PdfGenerator.GeneratePdf call and PdfDocument.save example in the issue, then trace the HTML-to-PDF rendering path involved in producing zh.pdf. Done means the supplied Chinese text, including 支持中文, renders correctly in the generated PDF.
