[XeTeX] Fake italics for some characters only

I am afraid that I do not understand why to make only 4 FakeSlant
characters instead of a FakeSlant font. Does it mean that other
characters will remain upright inside \textit?

Anyway, making a few characters active for \textit is quite simple.
Let's suppose that A and B should be active. You then define:

\def\mytextit{\begingroup \catcode`\A=13 \catcode`\B=13 \dotextit}

You will then call \mytextit{Test of A and B}
