my code:

            var loadOptions = new LoadOptions() {
                SpecifiedEncoding = CodePages.SimpChinese,
            };
            using (Image image = Image.Load("/Users/imac/Projects/CADExport/排产单 -  样板.dxf", loadOptions))
            {
                var cadImage = (CadImage)image;

                foreach (CadStyleTableObject style in cadImage.Styles)
                {
                    Console.WriteLine(style.StyleName + " - " + style.PrimaryFontName);
                }


                CadRasterizationOptions dwfRasterizationOptions = new CadRasterizationOptions();                

                dwfRasterizationOptions.PageHeight = 1000;
                dwfRasterizationOptions.PageWidth = 1000;

                PdfOptions pdfOptions = new PdfOptions();
                pdfOptions.VectorRasterizationOptions = dwfRasterizationOptions;

                image.Save("/Users/imac/Projects/CADExport/排产单 -  样板.pdf", pdfOptions);
            }

@liesauer,

We have investigated the issue on our end. Can you please check on your end that where the font was installed. The font must be installed in the folder: / Library/Fonts.

i checked just now, and i found the font is under /Library/Fonts/Microsoft, and i copy the font to both /Library/Fonts and ~/Library/Fonts. The first time, i got error message “Fontconfig warning: ignoring UTF-8: not a valid region tag”, so i copy the following lines into my .bash_profile and restart the bash
export LC_PAPER=en_US.UTF-8
export LC_ADDRESS=en_US.UTF-8
export LC_MONETARY=en_US.UTF-8
export LC_NUMERIC=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LC_TELEPHONE=en_US.UTF-8
export LC_MESSAGES=en_US.UTF-8
export LC_IDENTIFICATION=en_US.UTF-8
export LC_COLLATE=en_US.UTF-8
export LC_MEASUREMENT=en_US.UTF-8
export LC_CTYPE=en_US.UTF-8
export LC_TIME=en_US.UTF-8
export LC_NAME=en_US.UTF-8

the error gone, but still no chinese in the pdf, my dxf is utf-8 encoding.
btw, does the font must be installed in /Library/Fonts? because the fonts under /Library/Fonts/Microsoft can be found by the os and autocad.
