Seems we've seen this one before. The CSV output is likely not UTF8.

Here is one article: https://stackoverflow.com/questions/4348802/how-can-i-output-a-utf-8-csv-in-php-that-excel-will-read-properly

Then I found this on secure.php.net

if you want make UTF-8 file for excel, use this:

$fp = fopen($filename, 'w');
//add BOM to fix UTF-8 in Excel
fputs($fp, $bom =( chr(0xEF) . chr(0xBB) . chr(0xBF) ));

And this one looks much more elegant:

   
    $data = "Some utf-8 characters ąćżźćł" 
     
    header("Content-Type: application/octet-stream"); 
    header("Content-Transfer-Encoding: binary"); 
    header('Expires: '.gmdate('D, d M Y H:i:s').' GMT'); 
    header('Content-Disposition: attachment; filename = "Export '.date("Y-m-d").'.tsv"'); 
    header('Pragma: no-cache'); 
     
    //these characters will make correct encoding to excel 
    echo chr(255).chr(254).iconv("UTF-8", "UTF-16LE//IGNORE", $data);

Please test the latest commit in the 1.2.x branch for graph_xport.php. Excel does not detect it as CSV any longer, at least not automatically, but it still looks right.

Any feedback?
