Just to explain this part a bit more: on GUI frames, double-width
characters are not necessarily displayed at twice the width of other
characters from the same font; their actual width in pixels varies
with fonts.  This could cause one-column shifts in either direction
when using C-n/C-p across such characters.  I'm saying that what you
see in the minibuffer should be not worse than what you see in
"normal" buffers for those characters.
