Hmm, okay. Thank you so far.

But what's the correct way to encode the umlauts? I already experimented a lot with urlencode() and utf8_encode() but I'm not getting it right.

Code:

$query ='ö';
echo urlencode($query);

gives me the supposed ö. But using

Code:

$query ='ö';
redirect('results/'.urlencode($query).'/');

gives mit an url with results/ö/
