Description

I'm opening this issue again.

I need to convert html to pdf with jsPDF. It contains UTF-8 symbols (cyrillic). I used fontconverter to generate js-file for my custom font as written here: https://github.com/MrRio/jsPDF

So now example with text works like a charm (from https://github.com/MrRio/jsPDF/blob/master/examples/js/russian.js)

var pdf = new jsPDF('p', 'pt', 'letter');
doc.setFont('PTSans');
doc.setFontSize(10);
doc.text("А ну чики брики и в дамки!", 10, 10);

And example with html ignores my custom font and exports incorrect symbols.

var pdf = new jsPDF('p', 'pt', 'letter');
doc.setFont('PTSans');
doc.setFontSize(10);
pdf.html( "<html>А ну чики брики и в дамки!</html>", { callback: function (pdf) {
    var iframe = document.createElement('iframe');
    iframe.setAttribute('style', 'position:absolute;right:0; top:0; bottom:0; height:100%; width:500px');
    document.body.appendChild(iframe);
    iframe.src = pdf.output('datauristring');
    }
});

What I need to do to export html to pdf with unicode symbols?

Research direction

Start with the pdf.html() entry point and compare its font handling with the working examples/js/russian.js text example. Review how the fontconverter-generated custom font is used in both paths; done means the provided Cyrillic HTML renders with the custom font in the exported PDF.
