Arabic bidirectionality in Tkinter

[Salim Zayat]

Hey all.  I have a question about Tkinter and internationalization.  I 
have a unicode string:

s = u'\u0631\u062f\u062f\u0627\u063a'

When I send this to a canvas to be drawn as text:

canvas.create_text(x, y, text=s)

I get all the letters treated as individual characters, instead of 
changing their presentation in comparison to the characters around it 
(glyphs I believe theyre called).

Qt deals with this bidirectionality automatically, but Tkinter doesnt 
appear to.  What can I do?

Thanks for any help!
