I am using Aspose Word to convert DOC/ODT to PDF. The Doc has Simplified Arabic fonts (my machine also has Simplified Font included in font directory). But it seems that, while converting it to PDF the fonts are changed to Arial. PFA is the sample input and output documents. I have also added the screen shot of both document.
Thanks for your inquiry. We have converted the Word document to Pdf and have noticed that highlighted words in output Pdf have "Arial" font. For the sake of correction, we have logged this problem in our issue tracking system as WORDSNET-13640. You will be notified via this forum thread once this issue is resolved.
