Chinese characters in PDF output on Windows XP (Aspose.Word for .Net)

Dear all,

I am currently using Aspose.Word for .NET (version However I encountered an issue when generating a PDF containing chinese characters in a Windows XP SP3 environment: they are only displayed as rectangle boxes.
This Windows XP issue doesn’t happen when generating Word documents and there is no issue at all on Windows 7 environments (Word and PDF generation works just fine with Chinese characters).

I saw in the forum that you had a similar issue on Aspose.Word for java that has been recently solved. Could you please tell me if this issue has also been solved in Aspose.Word for .NET and, if it has been, from which version the correction is available ?


Hi Jacques,

Thanks for your inquiry.

First of all, please note that Aspose.Words requires TrueType fonts when rendering documents to fixed-page formats (PDF, XPS or SWF). Make sure you have all the Fonts installed on your XP machine you’re using to convert Word document to PDF format. I would suggest you please read the following article:

Secondly, I would suggest you please upgrade to the latest version of Aspose.Words 13.5.0 from the following link:

I hope, this helps.

Moreover, if the problem still remains, please attach your input Word document (.doc/.rtf files), output PDF document showing the undesired behaviour and Font(s) here for testing? I will investigate the issue on my side and provide you more information.

Best regards,

Thank you for your answer.
