Which part of the manual led you to expect the above behavior?

By default, Emacs only folds "canonically-equivalent" characters, and
those two aren't equivalent to 'a'.  If you want them to be found, you
need to customize the variables described in the manual to add more
variants.

I don't think this is a bug, Emacs is working as intended.
