[otrs] 2.1.1 in Internet Explorer

Hi everybody, I have two systems, one is OTRS 2.1.1 (productive) and one is OTRS 2.0.4 (test) I have a problem when I am using OTRS 2.1.1 with Internet Explorer and character " ' " is replaced by ' in all webpages (Ticket views, Sysconfig pages). In other browsers there is no problem (Opear, Firefox, Mozilla). Also in OTRS 2.0.4 everything is fine. So it looks like a change in the apache, any ideas?
