11.2 uncheck utf8 --> error

I am trying to install openSUSE 11.2 32bit on an ASUS Pundit Desktop (Model P3-P5G31). When I am in the menu with the installation overview and I go to Language → Details to uncheck the utf8 box it reports an installation error as soon as I start the install. But when I leave utf8 checked it works. Anyone else has seen this?
