In fact, it only works for Latin-1 text with no control characters.
If you want it to work for other types, don't use STRING.  E.g., you
can use type PIXMAP if you want graphics.  [I don't know how you do
that from Tk, though.  If you use type PIXMAP, the data should be the
pixmap's resource ID on the X server, not the content]

There's nothing limiting you to transferring plain text on X, any more
than on Windows (less, in fact; the X selection mechanism is *far*
more powerful than the Windows clipboard)

Try type='TARGETS'; that should get you a list of target types that
the selection owner is willing to provide.  Pick the one that you
want, and ask for that (it's possible to ask for several types at once
with type MULTIPLE, but I don't know how you'd go about telling it
what types you want, or where to put the results, using the interface
provided by Tkinter)
