Description:
can't possible to use cyrillic comment in routine

How to repeat:
-- --------------------------------------------------------------------------------
-- Routine DDL
-- --------------------------------------------------------------------------------
DELIMITER $$

CREATE DEFINER=`xx`@`xx` PROCEDURE `test`(IN in_test INT)
BEGIN

DECLARE l_test INT;

-- Начало

SELECT * FROM test WHERE id=in_test;

-- Продолжение

SET l_test=1;
SET l_test=l_test+2;

END

Click to Apply leads to correct saving of routine.
In console SHOW CREATE PROCEDURE test; views OK, but in workbench Alter Routine break text of routine like this:
-- --------------------------------------------------------------------------------
-- Routine DDL
-- --------------------------------------------------------------------------------
DELIMITER $$

CREATE DEFINER=`xx`@`xx` PROCEDURE `test`(IN in_test INT)
BEGIN

DECLARE l_test INT;

-- Начало процедуры

SELECT * FROM test WHERE id=in_test;

-- Продолжение

SET l_test=1;
SET

Probably a duplicate of bug #56083

Not exactly a duplicate, since the entire story is different. However, the problem ultimately goes down to the same bug in the underlying text control.
