+Vim has |imactivatefunc()| and |imstatusfunc()|. This is useful to
+activate/deativate input method from Vim in any way, also with an external
+command. For example, fcitx provide fcitx-remote command: >
+
+	set iminsert=2
+	set imsearch=2
+	set imcmdline
+
+	set imactivatefunc=ImActivate
+	function! ImActivate(active)
+	  if a:active
+	    call system('fcitx-remote -o')
+	  else
+	    call system('fcitx-remote -c')
+	  endif
+	endfunction
+
+	set imstatusfunc=ImStatus
+	function! ImStatus()
+	  return system('fcitx-remote')[0] is# '2'
+	endfunction
+
+Using this script, you can activate/deactivate XIM via Vim even when it is not
+compiled with |+xim|.
