Hi Rob,

finally I can dump and restore my db correctly with

mysqldump -u root -p --default-character-set=latin1 -d wikidb 
> '/home/klaus/backup.sql'

mysql -u root -p wikidb < '/home/klaus/wikidb.sql'

I did this for my local db and with this method I have no more charset 
problem ! That's what I am searching since a long time. There must be a 
problem with phpmyadmin, because saving and restoring with phpmyadmin 
creates charset problems if if I indicate "MySQL connection collation:" 

But now the great question: how can I do the same thing with my db on the web 
(ovh.net). Mysqldump does'nt work within phpmyadmin, so I can't execute it 

The manpage says: 
mysqldump is also very useful for populating databases by copying data from 
one MySQL server to another: 
shell> mysqldump --opt db_name | mysql --host=remote_host -C db_name

Is this the right way to dump my db remotely ? If yes, can you explain this 
command a little bit ? What is "remote_host -C" ?

Or is there a script to do it, for example dumpBackup.php ? Can I restore then 
with importDump.php ?

All this is quite new for me, I always used phpmyadmin or a scrit to upload my 
local db and I never had these problems.
