Although that's the best solution, if for some reason that can't be
done you can try using the "glitch" prompt escape to tell zsh what the
actual character width is.

PROMPT="%1{→%}"

tells zsh that although there are 3 bytes in the %{...%} sequence, it
should be treated as occupying only one character position.
