But I open this pdf with Adobe Acrobat Reader DC, word can’t be display normally. Can’ t we embed otf font into pdf?

    FileInputStream fileInputStream = new FileInputStream("C:\\Users\\xxx\\Desktop\\Aspose-Total-Java.lic");
    License license = new License();
    String out = "C:\\Users\\Lucy Hao\\Desktop\\12345.pdf";
    HtmlLoadOptions htmlLoadOptions = new HtmlLoadOptions();
    InputStream inputStream = new FileInputStream("C:\\Users\\xxx\\Desktop\\1234.html");
    Document document = new Document(inputStream, htmlLoadOptions);
    // check pdf font
    Document pdfDocument = new Document(out);
    for (Page page : pdfDocument.getPages()) {
        page.getResources().getFonts().forEach(font -> {
            System.out.println(font.getFontName() + ":" + font.isEmbedded() + "," + font.isSubset());
