Hi Team,
I am facing a an issue where if all of my variables in a docx document are not in same font, then few of them don't get replaced with actual values.
Below is the piece of code I use to replace variables and generate pdf, please advise what is missing
tempDir = correctDirectoryPath(tempDir);
			bytes = IOUtils.toByteArray(inputStream);
			file = new File(tempDir + fileName + this.formatter.format(new Date()) + ".pdf");
			WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new ByteArrayInputStream(bytes));
			VariablePrepare.prepare(wordMLPackage);
			MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();
			if (params != null) {
				fields = new HashMap<>(params);
				documentPart.variableReplace((HashMap<String, String>) fields);
			}
			Mapper fontMapper = new IdentityPlusMapper();
			wordMLPackage.setFontMapper(fontMapper);
			List<SectionWrapper> sectionWrappers = replaceHeaders(params, wordMLPackage);
			FieldUpdater updater = new FieldUpdater(wordMLPackage);
			updater.update(true);
			FOSettings foSettings = Docx4J.createFOSettings();
			foSettings.setWmlPackage(wordMLPackage);
			if (!file.exists()) {
				file.createNewFile();
			}
			os = new FileOutputStream(file);
			Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);
			System.out.println("Done!");
			return file;
