Is it possible to export Arabic and Chinese characters in pdf export

[sirishayalavarthi]

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();
}

here is HTML

@sirishayalavarthi, the PDF converter uses default fonts for conversion and the default fonts do not support all unicode code points. I have not yet resolved this issue or figured out how to get around it. See #181

A solution to the font problem is to define an embedded TrueType font in the style or stylesheet and set the body tag to use this font. OpenHtmlToPDF will use the characters from the font which has them defined.

For example including Noto Serif/Sans/Mono fonts and adding noto-serif, noto-sans and noto-mono families to CSS to allow PDF to use these for rendering text.

However, the PDF converter requires TrueType fonts and Noto CJK fonts are OpenFonts which cannot be used. The solution is to download a TrueType Unicode font that supports CJK character set and add it to the custom rendering profile to be used for PDF.

For my test I used arialuni.ttf from https://www.wfonts.com/font/arial-unicode-ms

If the installation directory for the fonts is /usr/local/fonts/ then the following in the stylesheet should be added:

@font-face {
  font-family: 'noto-cjk';
  src: url('file:///usr/local/fonts/arialuni.ttf');
  font-weight: normal;
  font-style: normal;
}

@font-face {
  font-family: 'noto-serif';
  src: url('file:///usr/local/fonts/NotoSerif-Regular.ttf');
  font-weight: normal;
  font-style: normal;
}

@font-face {
  font-family: 'noto-serif';
  src: url('file:///usr/local/fonts/NotoSerif-Bold.ttf');
  font-weight: bold;
  font-style: normal;
}

@font-face {
  font-family: 'noto-serif';
  src: url('file:///usr/local/fonts/NotoSerif-BoldItalic.ttf');
  font-weight: bold;
  font-style: italic;
}

@font-face {
  font-family: 'noto-serif';
  src: url('file:///usr/local/fonts/NotoSerif-Italic.ttf');
  font-weight: normal;
  font-style: italic;
}

@font-face {
  font-family: 'noto-sans';
  src: url('file:///usr/local/fonts/NotoSans-Regular.ttf');
  font-weight: normal;
  font-style: normal;
}

@font-face {
  font-family: 'noto-sans';
  src: url('file:///usr/local/fonts/NotoSans-Bold.ttf');
  font-weight: bold;
  font-style: normal;
}

@font-face {
  font-family: 'noto-sans';
  src: url('file:///usr/local/fonts/NotoSans-BoldItalic.ttf');
  font-weight: bold;
  font-style: italic;
}

@font-face {
  font-family: 'noto-sans';
  src: url('file:///usr/local/fonts/NotoSans-Italic.ttf');
  font-weight: normal;
  font-style: italic;
}


@font-face {
  font-family: 'noto-mono';
  src: url('file:///usr/local/fonts/NotoMono-Regular.ttf');
  font-weight: normal;
  font-style: normal;
}

body {
    font-family: 'noto-sans', 'noto-cjk', sans-serif;
    overflow: hidden;
    word-wrap: break-word;
    font-size: 14px;
}

var,
code,
kbd,
pre {
    font: 0.9em 'noto-mono', Consolas, "Liberation Mono", Menlo, Courier, monospace;
}
