DWG to PDF char encode on export

So, I’m trying to export a DWG to PDF and all looks good. Though, some special characters are not rendered accordly. Is there a way to set the char encoding on the result PDF output?

Here my code:

private ResponseEntity<byte[]> dwgToPdf(byte[] bytes) {

    val stream = new MemoryStream(bytes);

    val image = Image.load(stream.toInputStream());

    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
    rasterizationOptions.setBackgroundColor(Color.getWhite());
    rasterizationOptions.setPageWidth(1600);
    rasterizationOptions.setPageHeight(1200);

    // Create an instance of PdfOptions
    PdfOptions pdfOptions = new PdfOptions();
    // Set the VectorRasterizationOptions property
    pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

    // Export the DWG to PDF

    val os = new ByteArrayOutputStream();

    image.save(os, pdfOptions);

    return ResponseEntity.ok(os.toByteArray());

}
