You need to tell it what it is with the %{/%} and/or %G escape sequences. For
example, all of these are roughly equivalent and let zsh know that アイウエオ
takes up ten columns:

  PROMPT='%10{アイウエオ%}'
  PROMPT='%{アイウエオ%10G%}'
  PROMPT='%{%2Gア%2Gイ%2Gウ%2Gエ%2Gオ%}'

%{...%} without a leading digit or embedded %G is zero-width (useful for
invisible escape sequences).

(I don't think the behaviour of these sequences has changed since 5.2, but you
can check your zshmisc(1) to be sure)
