For encoding problems, add the following in the template string:

<meta charset="utf-8"></meta>

Like this:

let uri = 'data:application/vnd.ms-excel;charset=utf-8;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><meta charset="utf-8"></meta><!--[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]; }) }

Thank you

to change the default value of the download file :

var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,';
  var 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>';
  var base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))); };
  var format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }); };
  
  return function(table, filename, name) {
    if (!table.nodeType) table = document.getElementById(table);
    if (!table) {
      console.error("Table element with provided ID not found.");
      return;
    }
    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML};
    var downloadLink = document.createElement("a");
    downloadLink.href = uri + base64(format(template, ctx));
    downloadLink.download = filename || 'export.xls';
    downloadLink.click();
  };
})();
