JavaScript: how to Download CSV file containing French text with UTF-8 encoding

问题

I am trying to download CVS file using JavaScript. That CSV contains text in French language. I am creating file using blob

    var blob = new Blob([ csv ], {
                type : 'text/csv;charset=utf-8'
            });
    var csvUrl = window.URL.createObjectURL(blob);

But when i open the csv file it shows the content in ANSII format due to which French characters are converted to some unknown characters.

But if i open the same file as text, the encoding is ok (UTF-8).

Example: Text I am trying to download "Opération"
Text Visible in Excel (.csv) ==> Opération   <== With unknown characters
Text if opened in Notpad++ ==> Opération   <== Correct UTF-8

How can i open Download CSV file directly with UTF-8 encoding? I don't want user to change anything in excel. I want some javascript format so that excel could recognize all my characters irrespective of its encoding. Is it possible to do something?

The only thing to do is add the "\ufeff" at the beginning of your csv string:

var csv = "\ufeff"+CSV;
