问题

I want save a PDF with Sinhala unicode. but when try to convent data gives me junk data something like this "ʶ±Ê°ÀoÒ". If I cannot do this in jsPDF suggest me a another way but I do not want to use a screenshot like html2canvas.

let doc = new jsPDF('landscape'); 
doc.text(15, 30, 'ස්තුතියි');
doc.save("new.pdf");
