Generate PDF from SVG

[jhkst]

There is a js library to generate PDF from SVG (https://github.com/yWorks/svg2pdf.js/ ) that can generate PDF from SVG (so it is not necessary to include redundant PDF in sources).
Let's try it and if it works, remove the PDF (or make possible both - generate from SVG or use attached PDF)

Tried this code:

form-ular.html:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/2.3.1/jspdf.umd.min.js"></script>
<script src="lib/svg2pdf.umd.js"></script>

fu-svg.js:

async toPdf() {
        const svgE = $(this.svgElement).get(0);
        svgE.getBoundingClientRect();
        const width = svgE.width.baseVal.value;
        const height = svgE.height.baseVal.value;
        const pdf = new jspdf.jsPDF(width > height ? 'l' : 'p', 'pt', [width, height]);
        const font = await fetch('forms/jsd_14312/fonts/LiberationSans-Regular.ttf').then(res => res.text());
        pdf.addFileToVFS("LiberationSans-Regular.ttf", font);
        pdf.addFont("LiberationSans-Regular.ttf", "Liberation Sans", "normal");

        pdf.svg(svgE, { width, height }).then(() => { pdf.save('myPdf.pdf')});

    }

and when called it throws

for every rendered text.

The font is rendered properly after that, but unicode chars (glyphs, etc.) are rendered as from different encoding.
Eg.

'doručováno' => 'doru ovÆno'

Moreover Acrobat Reader reports 'The font LiberationSans-Regular.ttf' contains a bad /BBox'
