    First: Your header is malformed. It should be:

    <meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">

    And second: It should be into your template, because it contains charset information for Excel.

    <script type="text/javascript">
    var tableToExcel = (function() {
          var uri = 'data:application/vnd.ms-excel;base64,'
            , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
            , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
            , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
          return function(table, name) {
            if (!table.nodeType) table = document.getElementById(table)
            var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
            window.location.href = uri + base64(format(template, ctx))
          }
        })()
</script>

    if you want to change default file name according to @Axel Richter's answer, try this:

    var link = document.createElement('a');
link.download = 'filename.xls';
...
link.href = uri + base64(format(template, ctx));
link.click();
...

    replace window.location.href with link.href

    I will cite again a respect that was indicated above. You need to include the meta tag code inside the head tag:

    <head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta charset="utf-8" />
<!--This is what you should include-->
<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">
<!---->
<title>Ver Listado Pago</title>
<link href="/Images/Decretos.ico" rel="shortcut icon" type="image/x-icon" />
<meta name="viewport" content="width=device-width" />
<link href="/Content/site.css" rel="stylesheet" />
<link href="~/Content/booostrap/bootstrap.min.css" rel="stylesheet" />
<link href="~/Content/booostrap/bootstrap-theme.css" rel="stylesheet" />
<link href="~/Content/booostrap/bootstrap-theme.min.css" rel="stylesheet" />

    This has worked for me. But IE and WIN10 have some conflicts for download because of the xls extension. However, the problem of special characters is corrected

    Use the code below in the var uri:

    var uri = 'data:application/vnd.ms-excel;charset=UTF-8;base64,'

    Output

    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
