Does it?  I haven’t gotten it to work.

Evil also advices toggle-input-method.

Anyway, I feel that my solution of faking being in insert state while
isearch-forward-regexp is being run should solve the issue, but as I
mentioned, evil-state is re-entering normal state somewhere and I
can’t figure out when/how.  Evil’s solution in
evil-search-incrementally is better, but it doesn’t work for me.  I’m
actually getting

Invalid function: evil-without-input-method-hooks

when I try using / in 20150219.53.  Re-evaluating both it and
rewriting and then re-evaluating evil-search-incrementally as

(defun evil-search-incrementally (forward regexp-p)
  "Search incrementally for user-entered text."
  (let ((evil-search-prompt (evil-search-prompt forward))
        (isearch-search-fun-function 'evil-isearch-function)
        (point (point))
        search-nonincremental-instead)
    (setq isearch-forward forward)
    (evil-save-echo-area
      (evil-without-input-method-hooks
       (activate-input-method evil-input-method)
       (if forward
           (isearch-forward regexp-p)
         (isearch-backward regexp-p))
       (evil-push-search-history isearch-string forward)
       (deactivate-input-method))
       …

seems to solve the problem.  Only setting current-input-method isn’t
enough, as isearch-process-search-multibyte-characters checks
isearch-input-method-function, which is set to whatever
input-method-function was set to.
