Font sssue converting pdf to html

I have a pdf document produced by aspose:

<</Author()/CreationDate(D:20170825083052+02’00’)/ModDate(D:20170825083052+02’00’)/Producer(Aspose.Pdf for .NET 17.8)/Subject()/Title()/Creator(Aspose Ltd.)>>

The pdf has sections with different fonts (one of them being Calibri 11). When it is converted to html the section that has the Calibri 11 font is not formatted correct. All spaces are removed from the section and all lines ends with a “tf”.

A sample pdf can be submitted, code for converting the pdf document:

using (var ms = new MemoryStream(pdf))
using (var pdfDocument = new Document(ms))
var saveOptions = new HtmlSaveOptions
PartsEmbeddingMode = HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml,
LettersPositioningMethod = HtmlSaveOptions.LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss,
RasterImagesSavingMode = HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground,
FontSavingMode = HtmlSaveOptions.FontSavingModes.SaveInAllFormats
pdfDocument.Save(Path.Combine(tmpPath, fileName), saveOptions);
