problems with umlauts.

[eluser]helle[/eluser]
if i get_post a variable from i.e. an ajax request with

Code:

$this->input->get_post('name')

i get

Code:

hüdelü 5

but over the native php way

Code:

$_REQUEST

i get

Code:

hüdelü 5

, which would be the right value.

i looked into the input.php and saw that there is some xss cleaning stuff, which i don't want to loose. has anybody written a xss_clean method for CI which can handle umlauts?

thanks in advice ;-)
