export to pdf error (when Chinese in content )

@sholong, it is a limitation of the openhtmltopdf library which is used by the plugin.

The library needs additional fonts that have the necessary characters and html changes that will change the text to use those fonts.

This is covered by the issue for the library: danfickle/openhtmltopdf#129

I am looking into how this can be handled by the plugin.

@sholong, fixed in next EAP for non-latin fonts by including Noto Serif/Sans/Mono fonts with the plugin allowing 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

By creating a custom rendering profile for PDF export with CSS Text (see Rendering-Profiles-Settings):

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

.markdown-body,
.wiki-body {
    font-family: 'noto-sans', 'noto-cjk', Arial, "Helvetica Neue", "Segoe UI", freesans, sans-serif;
    font-size: 16px;
    line-height: 1.6;
}

var,
code,
kbd,
pre {
    font: 0.9em 'noto-mono', Consolas,Inconsolata,Courier,monospace;
}

And turning off all stylesheets and turning off HTML Generation option: Add page header for the custom profile.

Then setting Rendering Settings PDF profile to the above created rendering profile so PDF uses the custom CSS and HTML Generation.

Я ожидал увидеть в PDF текст и изображения такие же, как в превью
