Thanks for your inquiry. 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’re converting documents to PDF. Please refer to the following article:

How Aspose.Words Uses True Type Fonts

If you still face problem, please ZIP and attach ‘CordiaUPC’ and ‘Angsana New’ fonts here for testing. We will investigate the issue on our side and provide you more information.

Fonts are provided and problem occurs anyway.
