After poking around, the char-fold-table entry for \u1f77 contains
\u1f77 and \u03af, but not \u03b9, so this is expected. I then started
looking into the further details of unicode decomposition and
normalization, and decided that I definitely donʼt know enough about
this to decide if this is a bug or not :-)
