如何解决csv文件中特殊字符乱码？

Question

前端下载csv文件，代码如下：function downloadCsv() {       var csv = `"Name","Number"\n"Steampod 2.0 + Sérum + Creme de lissage cheveux epais + trousse glossy","15"`;    var csvFile;    var downloadLink;        csvFile = new Blob([csv], { type: "text/csv" });        downloadLink = document.createElement("a");        downloadLink.download = 'test.csv';        downloadLink.href = window.URL.createObjectURL(csvFile);        downloadLink.style.display = "none";        document.body.appendChild(downloadLink);        downloadLink.click();  }下载得到的文件打开如下，特殊字符这个要怎么处理？
