¿Cómo arreglar la consulta de funciones de creación mysql?

Question

Quiero agregar la función mysql:

CREATE FUNCTION `chf_get_translation`(translation_id INT, site_lang INT) 
RETURNS text CHARSET utf8
BEGIN

  DECLARE translation TEXT;

  SELECT title 
    INTO translation 
    FROM chf_translations 
   WHERE key_id = translation_id 
     AND lang_id = site_lang;

  RETURN translation;

END

Pero obtenga un error:

1064 - Tiene un error en su sintaxis SQL; Verifique el manual que corresponde a su versión del servidor MySQL para que la sintaxis correcta se use cerca de '' en la línea 3
