U+1F71 is what is called a singleton, having a single-character canonical
decomposition, which means that it is not used when recomposing.
Such characters are essentially clones that arrived in Unicode either
for roundtrippability or (in this case) because of a misunderstanding,
namely the belief that TONOS and OXIA were distinct accents.
