I know this is more related to Multiligual Language support in Wondows, but doesn't IE use the same thing? If it does you can uninstall the language support modules from within -
Control Panel --> Add & Remove Progs --> Windows Setup Tab --> Multilanguage Support. I presume it would be hear.
If you want to mess with the Language support IOD feature I think you go to the View Pull Down Menu in IE and select encoding.
I don't think thats what ya after though...Doh!....
