[XeTeX] Automatic language switching

I haven't tried your code, but I have triued to do something similar for Greek language texts:

\XeTeXinterchartokenstate = 1
\newXeTeXintercharclass \greekLetter
\XeTeXcharclass `\α \greekLetter
\XeTeXcharclass `\β \greekLetter
. . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . .
\XeTeXinterchartoks 0 \greekLetter = {\setlanguage{greek}}
\XeTeXinterchartoks \greekLetter 0 = {\setlanguage{american}}


 This works as expected and I think it is correct.
