The Unicode Standard v. 5.1 has a curl above in combination with ‘A’, ‘a’, ‘I’, ‘i’, ‘O’, ‘o’, ‘Y’ and ‘y’ in Latin Extended Additional. This curl, which is de- scribed as a hook in the Standard, is loose and has a different design from the fixed one used in e.g. Medieval Nordic sources. In fact, the latter form should rather be described as a reversed ogonek. For this reason ‘A’, ‘a’, ‘I’, ‘i’, ‘O’, ‘o’, ‘Y’, ‘y’ and a few other characters have been given separate code points in the list below. The Unicode Standard advises encoding characters of this type as a sequence of the baseline character and the COMBINING OGONEK ABOVE (1DCE), and this way of encoding has been given as an alternative for each character below.
