 It occurs on the letters a᷎ e᷎ i᷎ o᷎ ø᷎ u᷎.The ogonek should be almost the same size as a descender (relatively, its size in larger type may be significantly shorter), and should not be confused with the cedilla or comma diacritics used in other languages.Because attaching an ogonek does not affect the shape of the base letter, Unicode covers it with a combining diacritic, U+0328.
