We are using aspose.word version 13 to convert word to PDF using C# .Net. we have a new change to update the word to add new text. when deploying and using the service again we got a special characters for non- English text like small square with x inside. when undoing the change from the word the PDF is converted normally. the question and the issue is when open the existing word and update the content and save and close it. appreciate your help .
