OK that's a good point it explains everything.

Ok I did it but postgresql 7.4 was not very nice, the following failed :
1. dump
2. DROP DATABASE; CREATE DATABASE WITH ENCODING UTF8
3. restore

And it bugged. In fact the dump was writtent with "SET CLIENT
ENCODING=SQL_ASCII but when restoring on the UTF8 databse it failed, I
had to change it to SET client_encoding = LATIN1.

Anyway, finally everything is working again, I just had to add a SET
NAMES LATIN1 to my application because it was ISO and not UTF8 aware.

Therefore thanks a lot for your help, it solved all my problems !
