Encoding UTF-8 when exporting HTML table to Excel

Question

I am trying to export an HTML table to Excel using javascript. This is the javascript code

Answer 1

function exportData(report_id){
    var blob = new Blob([document.getElementById(report_id).innerHTML], {
        type: "text/plain;charset=utf-8;"
    });
    saveAs(blob, "Report.xls");

Takes table data as plain text and save as Excel without encoding problem
