Editing dump file before Import??

I've been trying to edit the .DMP file created by an EXP80, in order to change things like the tablespaces for tables and indexes. But when I try to use the edited file in an import, I get "IMP-00038: Could not convert to environment character set's handle."

Is there a CRC check on the file, or something else which makes this kind of operation impossible?

Or could it just be a typo in making the changes?
