Merge field displays Symbol as Alt Code


When using Aspose.Words to process a Merge field within a Word document (which specifically merges in a number of registered trademark symbols), the merged document displays the Alt Codes (®) instead of the Symbols (®). I’ve attached the original and merged documents (converted to pdf) for reference.

Is there any resolution to this issue?

Thank you,

We have discovered that the reported issue was caused by a lack of HTML decoding of the input string before it was provided to the MailMerge.Execute method.
