no problem :)
would be worth forwarding this on to the list (which I have done now
anyway).
then let serge have your app code to look at.
There IS an init method by the way, just that it doesn't seem to be
initialising the encoding variable (internal to the framework)

Hi;
I realise now what the problem is. The framework provides a init (with=20=
NO argument) method, so that you can have an object inited and use it=20
only later (using the connectTo:... method).
As I never used this method myself, I never realise that it got broken=20=
at some point (it is not using the same mysql API function to get the=20
encoding used).
Indeed, I think that I have documented a bit the method, saying it is=20
there so that one can set 'special' features for the connection BEFORE=20=
doing the connection... but I never needed such things, and never got a=20=
feature request, so it happily stayed in the TODO queue without moving=20=
further at any time. This is going to change as I want to provide the=20
possibility to use SSL for connecting to the DB server.
In short: You found a bug, thanks a lot for reporting it. I'll try to=20
fix it soon, in the mean time the easiest for you is to use John's tip.
I also realise that I have to make the corresponding part of the=20
documentation more clear.
Thanks again (Ezat & John), for pointing the bug to me.
Serge.
