I can reproduce the problem on the Linux console and the proposed fix
works for me: after disabling global-auto-composition-mode and then
visiting the file containing that text, the problem is gone.  (If I
first visit the file and then disable global-auto-composition-mode (or
just auto-composition-mode), I have to switch the buffer off the window
and then back to it in order to get the correct display.)
