Same issue with java version words-22.11-17.jar. Any update to the fix yet?
@serendipity.zhq Most likely the problem occurs because the font used the documents is not available in the environment where documents are converted to PDF. To build an accurate document layout the fonts are required. If Aspose.Words cannot find the fonts used in the document the fonts are substituted. This might lead into the layout differences due to differences in fonts metrics. You can implement IWarningCallback to get a notification when font substitution is performed.
The following articles can be useful for you:

Please try either installing or providing the fonts required to render the document. This should resolve the problem. If not, please attach your input and output documents along with problematic fonts here for testing, we will check the issue again and provide you more information.
