Subject: 24.3.50; Big screw: multibyte characters become unibyte
Date: Wed, 08 May 2013 04:21:30 -0400

When I use latin-1-postfix to enter characters such
as i-with-acute-accent and inverse-?, as soon as I type
another character they turn into Latin-1 single byte codes.

For instance, when I type i and ', the input method turns that into
i-with-acute-accent; but then my next keystroke turns the
i-with-acute-accent into \355.

This is horrible!

I can't find what is doing it.  It seems to happen no matter what the
next character is -- even M-x does it.  But I can't see this on
post-command-hook.
