The content (CJK characters) of the pdf generated by Aspose.Words is not always visible in a third party Silverlight pdf viewer. We contacted the pdf viewer support with two examples the answer from them was that in cases when the content was displayed by the viewer the pdf contains an embedded ToUnicode CMap for the used Type0 font and in cases when the content is not displayed by the viewer the mapping is empty in the pdf file. Is there a way to somehow force the inclusion of this ToUnicode CMap mapping? Do you have some information when Aspose.Words includes (or not) this mapping in the created pdf? We can reproduce this issue with both pdf compliance settings (PdfA1b, Pdf15) and EmbedFullFonts property is set to false.
We are using the Aspose.Words to generate pdf based docx documents. The attached files contains a working <> and a not working example <>.
