Chinese character problem when convert html to pdf

[ascylee84]

Hi,

I am using Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert to convert HTML to PDF.
Unfortunately HTML with chinese characters will displayed as ??? after save to PDF.
May I know how should I resolved this?

Example code:
string htmlCode = "<div style='font-family: Lucida, Helvetica, Arial, sans-serif; color: #333;'><h1 style='font-size: 18px; text-align: center; color:#666;'>接收记录</h1></div>"

var filepath = HttpContext.Current.Server.MapPath("//filename.pdf");

Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert(htmlCode, filepath,
true,
10 * 1000,
PdfPageSize.A4,
new PdfMargins(20),
LoadHtmlType.SourceCode
);

System.Diagnostics.Process.Start(filepath);

Thanks.

Hello,

Thanks for your inquiry!

Kindly note that you must make sure that your OS has the font that supports Chinese character before you convert the HTML code to PDF.

If the issue still exists after the font has been installed, please provide us with your OS information (E.g. Win7, 64 bit) and region setting (E.g. China, Chinese) for reference. Thanks in advance.

Sorry for replying late. Yeah the issue still there.
Here are the informations.

OS information : Windows Server 2016 Datacenter, 64 bit
Region setting : United States, English

I understand that the windows need to have the font to support Chinese characters. By default, there are some Chinese fonts available in the windows.
May I know what is the font used in Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert plugin which can support Chinese characters?

Thanks again

Hello,

Thanks for your feedback!

I noticed that the font-family (Lucida, Helvetica, Arial, sans-serif) of your html are Es fonts, they don't support rendering Chinese characters. I suggest that you first set a chinese font such as (Dengxian, Fangsong, Kaiti, Microsoft YaHei, Microsoft YaHei UI, simhei, Simsun, and Simsun extb) for you HTML string. Meanwhile, please make sure that the fonts you defined are installed on your system. Then convert your html to PDF. If the issue still happens, please porvide your generated PDF for our reference. Thanks in advance!
