Yep, the reason is that im trying to migrate the cluster from iso-8859-8
to UTF-8.

So I run a PHP script on an uncompressed dump, that replace few illegal
characters ( like long dash ) with the appropriate ones.
Then i run iconv and the result is fed to a UTF-8 cluster / db.

I tried handling the Custom dump, but its compressed.

Is there another practical way migrating the cluster beside dropping /
adding FK ? ?
