I discovered one more option to bring in m17n without affecting existing 
deployments.

M17n environments use XMODIFIERS to define X11 input methods (XIM). It is set 
to none for legacy X clients. E.g.
    $ XMODIFIERS=none squeakvm

Therefore, we can modify platforms/unix/vm-display-X11/sqUnixX11.c to check if 
XMODIFIERS is set to anything other than none. In that case, x2sqKey can parse 
UTF-8 sequences to UTF32 in utf32code and MacRoman in evt at: 3.
