It doesn't quite fix it, really: it only changes
enable-multibyte-characters in the current buffer, whereas the right fix
is to change the default (aka global) value to t.

Note that this global value is t by default, so something in your
configuration must change it to nil, and it's that thing that you need
to eliminate.  Maybe it's an EMACS_UNIBYTE environment variable, or
something in your .emacs.  Probably a left over from when you switched
to Emacs-20 where the multibyte code (i.e. "that Mule stuff") was still
suffering from various problems.
