csv 导出中的 æøå

Question

I'm trying to export some data into an CSV file i can download.

if im hitting my API in postman the data looks fine like:

Notat,Vare,Type,Størrelse,Tekst,Antal,Pris,Rabatprocent,Totalbeløb,Fakturerbar,"Lever nu",Faktureret,Lagersted,Placering,Lagerstyring
,,,,"Fadol 0,5 - 6 stk. ",4,,"0,00",1000,Checked,0,"0,00",,,Intet
,,,,"Classic 0,5",34,,"0,00",1700,Checked,0,"0,00",,,Intet
,,,,"Classic 0,5 - 6 stk ",3,,"0,00",750,Checked,0,"0,00",,,Intet
,,,,"Grimbergen 0,3",6,,"0,00",240,Checked,0,"0,00",,,Intet

,,,,"Sæson 0,3",2,,"0,00",80,Checked,0,"0,00",,,Intet

,,,,"Sodavand 0,5",102,,"0,00",4040,Checked,0,"0,00",,,Intet
,,,,"Fadøl 0,5",20,,"0,00",1000,Checked,0,"0,00",,,Intet
,,,,"Kop varme drikke",17,,"0,00",255,Checked,0,"0,00",,,Intet

But when i open the CSV file after downloading it will show Størrelse as Størrelse. Så it works fine in postman but not in the actual CSV file. someone can point me in the right direction for where my problem is?

Here is my code that creates the export:

//Open file pointer.        
        $fp = fopen('php://output', 'w');

        //Loop through the associative array.
        foreach($sortedData as $row){
            //Write the row to the CSV file.

            fputcsv($fp, $row);
        }

        //Finally, close the file pointer.
        fclose($fp);

        $response = $response->withHeader('Content-Type', 'text/csv; charset=utf-8');
        $response = $response->withHeader('Content-Disposition', 'attachment; filename="file.csv"');

        $stream = fopen('php://memory', 'r+');      

        return $response->withBody(new \Slim\Http\Stream($stream));

depends on encoding type. I got similar issue with csv file.I converted the row to "ISO-8859-1" ( for german characters) .

 iconv(mb_detect_encoding($text), "ISO-8859-1", $text);
