I want the name of the file to be that string + .csv ( "$name.csv" ). For a western character set I can do this just fine by doing: header("Content-Disposition: attachment; filename=\"$name\""); But for other character sets, the download file's name is garbage letters + .csv (such as ×œ×œ× ×›×•×ª×¨×ª.csv )
