One of our users complained that bash-5.1 on Solaris 11.4, when started
with LANG=C does not allow Unicode input after changing LANG to a UTF-8

I've confirmed this is the default behavior, but can be overridden by
manually changing the readline output-meta flag fro

Well I'll be. I had to write a script to test it becaus

Understanding now that traps are more literally like inserting an eval,
what makes return in the top level trap string special is that there are
two script paths behind it so its reasonable the the coder of the trap

The language in the standard for return was clearly based upon the
idea that it should act just the same as exit, which is not really
appropriate.
