When doing a preview in my forums [rc1] the umlauts and every special character is displayed wrong. If I visit this forum here with the same browser, everything looks ok. The charset is set to iso-8859-1 in the generic language file. Changing that to anything else (tried iso-8859-15 or UTF-8) does not show any change. What else can I do?

Example:
äüö
Preview shows:
äüö
