what does" di piu poi si sa" mean in Italian or French please?

more than that is then known

We know then more than that-.

It may also mean:in addition to this we also know that...............

If you can give the context, that would help

It's Italian but something is missing.

Propabily the correct sentence is:

"un giorno si saprà di più" which means: "one day we'll know more"

another possibility is:

"poi si sa" which means "everybody knows"

it's wrong in italian and it's not french.

its italian: it means

everything else, then you know

with the meaning that you know all the rest of the thing you're talking about.

It's a bit hard to translate that by itself, please add more context.

More, then, it is known... in italian.

shure it is not "pUoi"?
