Aspose.PDF Product Family

I am trying to generate pdf from xslfo and am experienced with the font issues
FontRepository.Sources.Clear();
FontRepository.Sources.Add(new
FolderFontSource(_fileSystem.GetAbsolutePathFor(Path.Combine(“Document”, “Fonts”))));
var defaultFont = FontRepository.FindFont(“Open Sans Regular”);

using var document = new Aspose.Pdf.Document(xslFoStream, new XslFoLoadOptions());

After document instance created: document.FontUtilities.GetAllFonts() returns list of fonts (Arial, Times New Roman)

var pdfStream = new MemoryStream();
document.Save(pdfStream, new PdfSaveOptions { DefaultFontName = defaultFont.BaseFont });

After saving target font has not been applied. Please advise.

I have created .Net Core console application which based on XslFO, generates pdf files using fonts stored in the solution.

actualResult.pdf - represents generated file
Actual result: font in pdf fall back to Times New Roman (on docker pod it is fallback to DejaVu Sans)
Expected result: pdf rendered with specified fond (OpenSans.ttf)

Also, is there any documentation or guide on how to configure fontconfig on my debian docker container to avoid using the default DejaVu?

Please advise
