                Click on the "Menu" on the top-left corner of frame.

                The menu should have four entries:
                1) a row of five unicode characters: \u00c4\u00cb\u00cf\u00d6\u00dc
                2) a menu separator
                3) a unicode character:  \u012d
                4) a unicode character:  \u022d

                If the menu items look like the list above, the test passes.
                It is okay if the unicode characters look like empty boxes
                or something - as long as they are not separators.

                If either of the last two menu items show up as separators,
                the test FAILS.

                Press 'Pass' if above instructions hold good else press 'Fail'.""";
