Hi
the OFDB.DE.TXT script needs some more lines in the SUBSTITUTETAGS section.
Try to add following 7 (bold) lines, to have german umlauts translated:
#SUBSTITUTETAGS#
#SUBSTITUTEWORD#=%E4=ä
#SUBSTITUTEWORD#=%C4=Ä
#SUBSTITUTEWORD#=%F6=ö
#SUBSTITUTEWORD#=%D6=Ö
#SUBSTITUTEWORD#=%FC=ü
#SUBSTITUTEWORD#=%DC=*
#SUBSTITUTEWORD#=%DF=ß
#SUBSTITUTEWORD#= =
#SUBSTITUTEWORD#=¡=¡
#SUBSTITUTEWORD#=¢=¢
#SUBSTITUTEWORD#=£=£
#SUBSTITUTEWORD#=¤=¤
Does it work for you?
