Exporting rare Chinese characters to PDF results in them not being displayed. The following is a sample code, using the Stimulsoft.Reports.Engine.NetCore 2023.3.1 version.
The attachment contains report.mrt and msyh.ttf.
Code: Select all
private void button1_Click(object sender, EventArgs e)
{
Stimulsoft.Base.StiFontCollection.AddFontFile("..\\..\\..\\data\\msyh.ttf", "微软雅黑");
using (var stiReport = new Stimulsoft.Report.StiReport())
{
stiReport.Load("..\\..\\..\\data\\Report.mrt");
stiReport.Render();
stiReport.ExportDocument(Stimulsoft.Report.StiExportFormat.Pdf, "..\\..\\..\\data\\Report.pdf", new Stimulsoft.Report.Export.StiPdfExportSettings { EmbeddedFonts = true });
}
}

Hello,
Please try to add the used font to the font collection:
Stimulsoft.Base.StiFontCollection.AddFontFile();
Thank you.

Please look at the code above, it already has the addition of Stimulsoft.Base.StiFontCollection.AddFontFile.

Hello,
Most of the standard fonts do not contain national characters. In this case, Windows uses the "font fallback". This algorithm is very complicated and, therefore, is not realized in the exports.
To output national characters, please, use the font which contains all necessary characters. For example, the "Arial Unicode MS" font contains many national characters.
In your case, try to use the SimSun-ExtB font.
Thank you.

Tried using SimSun-ExtB, but got the same result, the PDF export doesn't display.

You should use the font that contains all the used symbols.

I used this font AlibabaPuHuiTi-3-35-Thin.ttf, and I have checked this font with FontCreator which includes the relevant characters, but there is still a problem exporting to PDF.
