Adding HTML with font-family inconsistent behavior

Aspose.Total Product Family

Using Aspose.Words DocumentBuilder.InsertHtml and Aspose.Slides Paragraph.AddFromHtml has inconsistent behavior taking over the CSS font-family.

Example HTML:

<span style="font-family: &quot;poppins&quot; , &quot;abc&quot;">Hello World</span>

In Aspose.Words the font will be the last value of the CSS font-family values (e.g. "abc" in example below).
In Aspose.Slides the font will be all values of the CSS font-family (e.g. "poppins, abc" in the example below).

I would expect that Aspose would only take the first CSS font-family value (e.g in the example below it would just take "poppins".

See code below for reproduction:

using Aspose.Slides;
using Aspose.Words;
using System.Diagnostics;
    
var document = new Document();
var builder = new DocumentBuilder(document);
builder.InsertHtml("<span style=\"font-family: &quot;poppins&quot; , &quot;abc&quot;\">Hello World</span>");
document.Save("test.docx", SaveFormat.Docx);
    
using (var presentation = new Presentation())
{
    var text = presentation.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 0, 0, 100, 100).AddTextFrame("test");
    text.Paragraphs.AddFromHtml("<span style=\"font-family: &quot;poppins&quot; , &quot;abc&quot;\">Hello World</span>");
    
    presentation.Save("test.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}
    
// Font will be poppins, abc (=> all values)
Process.Start(new ProcessStartInfo { FileName = "test.pptx", UseShellExecute = true });
    
// Font will be abc (=> last value)
Process.Start(new ProcessStartInfo { FileName = "test.docx", UseShellExecute = true });

@kaiwachter “Poppins” is an MS Cloud font. AW will use it if the font will provided explicitly. Currently AW do not download MS Cloud fonts and do not use MS cloud fonts folder "%USERPROFILE%\AppData\Local\Microsoft\FontCache\4\CloudFonts" as a font source. As a workaround you could add folder font source to MS cloud fonts folder (if running Aspose.Words on a machine where MS Word downloaded the font) or provide this font by other means.
It is highly unlikely that we will implement loading cloud fonts due to licensing. So the issue will be closed as “Not a Bug”.
