I've tested the issue with Aspose.Words 6.0.1 and Aspose.Pdf 3.9.0.0 and I am able to notice the same problem. After investigation I've noticed that the issue is occurring at Aspose.Words end, where the spacing information between "der E mittentin" is not being exported into the intermediate XML file. We are working in coordination with Aspose.Words team to investigate the reasons of this issue and to get it resolved, and will keep you updated with the status of correction.
For the time being I've modified the XML file and have generated the Pdf file which does not contain the issue that you have reported. Please take a look and let us know in case of any further issue.
