[otrs] uarr / darr for StatusView columns

Hello, We have just upgraded from 2.1.7 to 2.2.1 on CentOS 4 (using the Fedora Core 1-3 RPM, which has always worked just fine). After running the database upgrade script all seems to be working fine. There is one strange thing though: in StatusView there should up and down arrows for every column to be able to sort, but instead of the arrows we see ↑ and ↓. Looking at the page source I see ↑ which of course isn't going to work. Should be ↑ I guess. Anyone else seeing this? Nils Breunese.
