Aspose.PDF Product Family

Hi,

The following C# code snippet results in a NullReferenceException when calling the Aspose.Pdf.Document constructur:

byte[] contentBytes = Encoding.UTF8.GetBytes(mbContent);
using(MemoryStream ms = new MemoryStream(contentBytes))
{
  mailbodyDocument = new Document(ms, htmlLoadOptions);
}

The content of the variable mbContent is as follows:

<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:m="http://schemas.microsoft.com/office/2004/12/omml" xmlns="http://www.w3.org/TR/REC-html40"><head>

The exception seems to be caused because of the font ‘Segoe Print’:
<span style="font-family:&quot;Segoe Print&quot;">
Simpy changing the html tag to e.g.:
<span style="font-family:&quot;Calibri&quot;">
fixes the problem.

The font is locally installed in Windows.

Any help is appreciated,
Thanks
