60’s to 80’s movie, possibly foreign, teen/child adventure film

Everytime I Google the basis of the film, it gives me Madeline, which sounds similar at first glance but outside the time period. I believe it’s based in the Middle east but possibly Mediterranean area like Greece/Italy. Time period is set anywhere from 40’s to 60’s… The main character is a girl in age from 10 to 12, possibly orphaned. She is a bit mischievous. She meets a local boy who at first she is at odds with but later befriends. I remember a scene where both or one of them is running from someone, they end up on the roof of the building outside her window. They have a conversation about street smarts. And one of them (likely the girl) takes out a face powder compact and shows the other to blow powder in the face of the pursuer. At one point, I believe someone helps them hide, possibly from a corrupt constable/policeman. While they are hiding they try and change clothes to change appearance I believe. Later on again, they use the powder trick to actually escape. Eventually it’s a happy ending and the film ends with a nun or teacher yelling at the little girl to come down as she is walking along the top of an old brickwall…
