Provide a dialog where the user can configure localization settings

I would expect there to be a simple way that the user can cofigure what language they want to use for their desktop and how numbers should be presented, default currency etc. In fact a user may speak multiple languages so they should be allowed to give a preferred list of languages. If an app can't present itself in the first language then it tries the next one.

KDE has this but I cannot find the equivalent in GNOME. I know it is possible to set the language at the GDM login screen but that is not adequate. I have users that login remotely and thus don't go through GDM. Also the other settings like currency and how to display numbers cannot go on the GDM screen anyway! Every other OS has these features so I think this is quite a significant problem for Ubuntu and GNOME.
