With the following qml:
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.
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.
