With the following qml:

        Text {
            text: "مصر yooo مصر yooo."
        }

and cpp:

app.setLayoutDirection(Qt::LeftToRight);

The rendered output looks like this:

According to the documentation, the QGuiApplication.layoutDirection can be used to explicitly set base direction for the text (a.k.a. embedding level in BiDi spec). The rendered output acts as if Qt::LayoutDirectionAuto was set. With Qt::LeftToRight, the expected string should be rendered in reverse order and the dot should be on the right side.

From https://doc.qt.io/qt-6/qt.html#LayoutDirection-enum:

When LayoutDirectionAuto is used in conjunction with text layouting, it will imply that the text directionality is determined from the content of the string to be layouted.
