I have tried to download some Arabic characters and Chinese characters showing ###

this is the code in the parser

public byte[] generateFile(final String markdown) {

    Node document = getParser().parse(markdown);
    String html = getRenderer().render(document);
    String htmlDoc = applyCssStyling(appendHtmlAndCssTag(html));

    System.out.print(htmlDoc);
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    PdfConverterExtension.exportToPdf(out, htmlDoc, null, getFlexOptions());
    return out.toByteArray();
}
