Encoding Problem

Hi,

after upgrading from 3.2.1.2 to 3.3.0.7 we are seeing massive problems. Site is ojs.uni-passau.de
Especially the encoding (site is in german) ist not working. DB is UTF-8 and the content is stored correctly (with umlaut).
DB upgrade ran.
My config looks like this:

;;;;;;;;;;;;;;;;;;;;;;;;;
; Localization Settings ;
;;;;;;;;;;;;;;;;;;;;;;;;;

[i18n]

; Default locale
locale = de_DE

; Client output/input character set
client_charset = utf-8

; Database connection character set
; Must be set to “Off” if not supported by the database server
; If enabled, must be the same character set as “client_charset”
; (although the actual name may differ slightly depending on the server)
connection_charset = UTF8

; Database storage character set
; Must be set to “Off” if not supported by the database server
database_charset = Off

; Enable character normalization to utf-8 (recommended)
; If disabled, strings will be passed through in their native encoding
; Note that client_charset and database collation must be set
; to “utf-8” for this to work, as characters are stored in utf-8
charset_normalization = utf-8

What can I do?
