Download BLOB content using specified charset

Question

Is possible to change the Blob charset really? I'm trying it for hours but it doesn't workds. See this.

jQuery("#download").click(function() {     var csv_content = jQuery("#csv").val(),         download = document.createElement("a"),         blob = new Blob([csv_content], { type: "text/csv;charset=ISO-8859-1" });      download.href = window.URL.createObjectURL(blob);     download.download = "test.csv";      var event = document.createEvent("MouseEvents");     event.initMouseEvent(         "click", true, false, window, 0, 0, 0, 0, 0         , false, false, false, false, 0, null     );     download.dispatchEvent(event);     }); 

I need export a CSV to open on Excel, but it always is save with UTF-8 and Excel can't handle it.

Answer 1

I found the solution before to post.

The change of charset has not been resolved, in fact. However, I sent the UTF-8 header for the download process and Excel was able to understand the file format correctly. Thanks to this response of Erik Töyrä.

blob = new Blob(["\ufeff", csv_content]);
