Hi!

I have just upgraded a site from 4.6.2 to 4.8.0. The site is in swedish and I have experienced that the globalization culture in web.config that has worked best for swedish language has been "iso-8859-1" . I have used it in several sites in earlier versions of DNN. 

But now after upgrading to DNN 4.8.0 I get some weird characters in page title, or module title when updating a page or module settings. The swedish characters Å, Ä, Ö is being replaced by characters as Ã… Ä Ö Ã¥ ä ö . Those are definitively not swedish characters....

If I change to "utf-8" in web.config then it works almost fine, except that in custom modules, or in skins where I have coded swedish characters is being replaced now by a � character. (Yes, a square)
I can solve this in my skins or custom modules, but one more problem is that if I use the Iframe module and display an external page, that page also shows wrong characters and the page is out of my control... 

What change has been done in DNN 4.8.0 that is causing this? 
Can this be solved, or do I have to roll back to my previous versions of DNN ?
