I have created a two pdf file from html by using two different pdf libraries
first is openhtmltopdf-box library
second is mpdf library

the content of pdf is hindi
and both library created a pdf successfully
but the pdf in first library is not rendered properly in pdf but when i copy the same content from that pdf and paste it anywhere the content is render properly

now in second library the content is rendering properly in pdf but when i copy the same content and pasting anywhere it is changed
there is a problem in hindi text where two letters or matras are mixed
what is the problem here and how to resolve this

below is the content i am showing u

actual text = “वर्तमान”
first library is showing some other text but when i copy and paste here then it will become proper

second library text showing proper in pdf but when i copy it and paste here it becomes
“वतमान”

I am just comapring my problem with other library, but i am using openhtmltopdf-box library and how to resolve this problem in this library for rendering a content properly in pdf file.

source code :

public byte[] startPdfCreation(PdfRendererBuilder builder, String template, PdfConfiguration configuration) {
  try (ByteArrayOutputStream os = new ByteArrayOutputStream()) {
    builder.useFastMode();
    Document document = Jsoup.parse(template, "UTF-8");
    builder.withW3cDocument(new W3CDom().fromJsoup(document), "/");
    builder.usePageSupplier(new BackgroundImageHandler(configuration.getLetterheadContent()));
    builder.toStream(os);
    builder.run();
    return os.toByteArray();
  } catch (Exception e) {
    log.error("Error while creating a PDF", e);
  }
  return new byte[0];
}
