I am using Aspose for merging the documnets. When attaching a documnet with a special character in file name, getting FileCorruptedException.
Have you tried the latest (20.6) version of Aspose.Words for .NET on your end? In case the problem still remains, please ZIP and upload your input Word document you are getting this problem with here for testing. We will then investigate the issue on our end and provide you more information.
