Please note that Aspose.Words requires TrueType fonts when rendering document to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts that are used in your document on the machine where you are converting documents to PDF. Please refer to the following articles:

Manipulating and Substitution TrueType Fonts

We have attached the output PDF with this post for your kind reference. 21.1.pdf (107.9 KB)

Is it compatible with Aspose.word version 13 ?
