What TFMXRTL affecting?

TFMXRTL, changes some core objects of FireMonkey, which are responsible for text presentation. Because of the fact that we correct, core classes almost every text related action, in FireMonkey will be corrected. For example any of the commands below will work as expected.

Label1.Text := 'some arabic text';
(live binding)
Canvas.FillText(ARect, 'some right to left text', True, 1, [RightToLeft], TTextAlign.Trailing);


Does it affect text generation, in any way?

Processing a bidi text is a lot more complex than processing a single direction text. But with our fast algorithm the effect is minimized the way that you won't feel it in a real environment.
