Converting eml to pdf with german header

We are evaluating Aspose total for rendering files to PDF. When trying to render EML to PDF the header is automatically in english. We copied an example code for it. Every example we found uses .mhtml as a step between.
Code used:
LoadOptions options = new EmlLoadOptions();

			MailMessage eml = MailMessage.load(source, options);
			String tempPath = FileUtils.dirOnly(source) + "temp.mhtml";

			MhtSaveOptions defaultMhtml = SaveOptions.getDefaultMhtml();
			eml.save(tempPath, defaultMhtml);
			com.aspose.words.LoadOptions lo2 = new com.aspose.words.LoadOptions();
			lo2.setLoadFormat(LoadFormat.MHTML);
			Document doc = new Document(tempPath, lo2);

			PdfSaveOptions pso = new PdfSaveOptions();
			pso.setCompliance(PdfCompliance.PDF_15);
			doc.save(target, pso);

How can we change it so the header is in german language?
