Hi, it´s a long time, but I also have problems with german umlaut - for me I have the solution, I hope it is also yours.
The problem is that if you have an umlaut such as in Münster the urlencode converts this not compatible to vcard. In vcard you will see Münster, but vcard needs ü not converted. You need a decimal unicode. So an ü must become ß See on this site: http://andrewu.co.uk/tools/uriencoder/ Ok, my solution: I get my content from database <?php $text = htmlentities($row->name); // htmlentities macht aus Umlauten ä usw. // vcard will aber einen dezimal Unicode also ä für das ä // wandelt ä,ö,ü,ß,A,Ö,Ü um $von = array("ä","ö","ü","ß","Ä","Ö","Ü"); $zu = array("ä","ö","ü","ß","Ä","Ö","Ü"); $text = str_replace($von, $zu, $text); $vcard = 'BEGIN:VCARD VERSION:2.1 N:' . $text . ' TEL;WORK;VOICE:' . $row->telefon . ' TEL;MOBILE;VOICE:' . $row->mobil . ' EMAIL;PREF;INTERNET:' . htmlentities($row->email) . ' URL:' . htmlentities($row->web) . ' END:VCARD'; $vcard = urlencode($vcard); ?> <img src="https://chart.googleapis.com/chart?chs=200x200&cht=qr&chl=<?=$vcard?>&choe=UTF-8" > This works fine for me . if somebody knows an other method please reply here.
