Thanks for the idea, but the volume is too heavy and performance
problems already too important on the original database to overload it
with an additional daily dump.
This is not just a one-shot issue. The analysis tool I am setting up is
made to continually analyze the activity of my company.

Would there be a way to get the binary content of text field ?
Maybe that could be the solution, performing the encoding conversion at
the application level, then.
