This is mysterious. ISO 233-1984 shows under "Vowels and diphthongs": aw° ay° The ring/circle is printed *after*, not above the letter, which suggests spacing U+02DA. ISO 233-1984 identifies this ring/circle to have code position 4/10 in ISO 5426. ISO 5426-1983 defines character 4/10 as non-spacing "circle above" that *precedes* the letter, whereas U+030A follows the letter.
