Hi Vladimir,
at the moment I don't see any reason why we should ever change the character encoding. But anyway, thanks to your input and due to our research into the other DBMS's it seems we have to switch to CLOB fields (or text, varchar(max) fields respectively) anyway, so that the length limitation problem will be no issue anymore, however we will have to deal with other headaches, like implementing text search within those long fields in our code for all DBMS's involved.
Cheers
