SOLVED: Can I force CI not to cut off post data when reading special character?

[eluser]meddiecap[/eluser]
Hi,

I've been working on a simple and small cms for a simple site. During tests i found out that CI on PHP 5.3 (5.4?) doesnt handle posts with special characters too well.

I've tried to turn off some sanitizing/cleaing function in CI's core, but nothing helped. I don't really know where to do this.

Several threads handle this problem but I havent found a solution. E.g.:
http://ellislab.com/forums/viewthread/84802/

So, as the title says: Can I force CI not to cut off post data when reading special character?

That way I won't get data cut in half. I figured I can do some sanitizing myself.

I hope someone can shed some light on this.
Thanks.

EDIT: I found out it had to do with CKEditor, which by default strips out all the special characters. Had to set these configs to false: entities, htmlEncodeOutput
