[otrs] utf8 vs. iso-8859-1 with external Customer database

Hi, When we use the CustomerUser::DB to get customer data into our helpdesk extended chars looks bad. If we change the Default CharSet to iso-8859-1 (in the config.pm) it's just fine, but then we get problems with chars in internal mails and some views in the interface. In the LDAP module we have the option to define source and destination charset: SourceCharset => 'utf-8', DestCharset => 'iso-8859-1', I would very much like to do some thing like that with the database module. Anyone who knows how?
