ctext works for me, the same as iso-2022-7bit (which C-h h uses).
Those coding systems store composition information as escape
sequences, so post-conversion isn't relevant for them (unlike utf-8).

Is the width being wrong a severe problem somehow, or is the severity
mentioned in the subject just the lack of composition?  (I ask partly
because character width is currently somewhat ambiguous in Emacs 22,
e.g. for non-CJK characters from CJK coding systems.)

What bug?  I can't see a log message.
