I haven't looked into the issue but from Christian's post it sounded
like the BMP limitation was deeper inside Tcl/TK and would take more
serious work to fix. How many people really care?

Given that most tk apps aren't text heavy, UTF-8 seems fine: when has
the O(n) indexing been found to be a real problem in practice?

Hmm interesting. Then there's also lots of new targets like mobile
phones which Tk hasn't been ported to Afaik.

Tcl itself is reasonably small and portable, the problem is the bindings
(C code) to all the different window systems Tk supports.
