The attached file was created by TextEdit on the Mac. It displays with two lines in Word. However, the Aspose library doesn’t seem to recognize the last line. You can verify this by loading it with your sample CSharp demo app DocumentExplorer.
Thanks for your request. I managed to reproduce this problem. This is known problem (issue #4058). We will notify you as soon as it is done.
We have released a new version of Aspose.Words that contains a fix for this issue.
