Step 2: Add Aspose PDF Library to the Project
Add the Aspose PDF for Java library to your project by following these steps:
> Right-click on the project > Build Path > Add External Archives... Select the aspose-pdf-xx.x.xx.jar file (downloaded in the prerequisites) and click "Open"
Step 3: Create a PDF Document with Umlauts
Now, let’s create a PDF document with umlauts using Aspose PDF. Create a new Java class and add the following code:
import com.aspose.pdf.Document;
import com.aspose.pdf.Font;
import com.aspose.pdf.FontRepository;
import com.aspose.pdf.Page;
import com.aspose.pdf.TextFragment;
public class CreatePDFWithUmlauts {
public static void main(String[] args) {
// Create a new PDF document
Document document = new Document();
// Add a new page to the document
Page page = document.getPages().add();
// Create a new font with umlauts support
Font font = FontRepository.findFont("Arial Unicode MS");
font.setScale(new Font.FontScale(12));
// Create a text fragment with umlauts
TextFragment text = new TextFragment("Umgebung, Übung, and Änderung");
text.setFont(font);
// Add the text fragment to the page
page.getParagraphs().add(text);
// Save the PDF document
document.save("C:\\Users\\User\\Documents\\AsposePDFUmlauts.pdf");
}
}
Step 4: Save the PDF Document with Umlauts
Run the above code and it will save a PDF document with umlauts to the specified location. Open the PDF document to verify that the umlauts are displayed correctly.

Frequently Asked Questions
Saving Aspose PDF documents with umlauts can be a bit tricky, but don’t worry, we’ve got you covered!
Q: Why do my PDFs not display umlauts correctly when saved using Aspose?
This is because the default encoding used by Aspose is not set to handle special characters like umlauts. You need to specify the correct encoding when saving your PDF document. Try using `doc.save(“output.pdf”, new PdfSaveOptions { EnableFontHinting = true, Encoding = Encoding.UTF8 });` to ensure that your umlauts are displayed correctly.
Q: How do I ensure that my PDF document is saved with the correct font to display umlauts?
To ensure that your PDF document is saved with the correct font to display umlauts, you need to use a font that supports these special characters. Try using a font like `Arial Unicode MS` or `Open Sans` which has extensive character coverage, including umlauts.
Q: Can I use a different encoding scheme to save my PDF document with umlauts?
Yes, you can use a different encoding scheme to save your PDF document with umlauts. For example, you can use `ISO-8859-1` or `Windows-1252` encoding schemes, but keep in mind that these schemes may not support all special characters. It’s recommended to use `UTF-8` encoding for maximum compatibility and character coverage.
Q: Why are my umlauts displayed as question marks or squares in my PDF document?
This is usually because the font used in your PDF document does not support the umlauts or the encoding scheme used to save the document is not correct. Try using a font that supports umlauts and ensure that the encoding scheme is set to `UTF-8` when saving the document.
Q: Can I use Aspose to save PDF documents with other special characters like accents or diacritics?
