It's probably because the content type of all pages being served by the AppDB have been changed to utf-8. Someone will need to write a patch to change it back to ISO-8859-1.
Are you sure the change wasn't intentional?
I asked about this on wine-devel before I started fixing things manually, but never got a clear response, or any real interest in the problem.
