Encoding UTF-8 when exporting HTML table to Excel

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

<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"><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>

This is my header

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

This is my table

<table id="tblExport">
   <tr>
      <td>José</td>
      <td>María</td>
   </tr>
</table>

And this is the button which triggers the export

<input type="button" onclick="tableToExcel('tblExport', 'W3C Example Table')" value="Export to Excel">

I can't export the UTF-8 characters correctly, like é or í. I try this Importing HTML table into OO Calc as UTF8 without converting to entities but not works. I have MS-Excel 2010 and Win7 64 bits.

How can I do to export UTF-8 chars correctly?

Thanks!

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

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>

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

Use the code below in the var uri:

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