Some more thoughts about this one.

Just remembered of a parameter nls_length_semantics. Default value for it is BYTE. But one can either alter system or session to CHAR and then all newly created tables (and it seems executed programm units as well) uses character length semantics.
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96536/ch1121.htm#REFRN10124 So it seems you can set this parameter on DB level and import should run fine... Don't know if it has any other possible downsides though.
