The Unicode Standard v. 5.1 has no precomposed characters with both ring above and circumflex. The present subrange contains one precomposed charac- ter with this combination. The Unicode Standard advises encoding characters of this type as a sequence of the baseline character and the COMBINING RING ABOVE (030A) and the COMBINING CIRCUMFLEX ACCENT (0302), and this way of encoding has been given as an alternative for the character below.
