It's easy for things like “ⓐ” or “á”, which are single characters,
normalizing a combination of multiple characters (like “á”) can get a
little complicated. But then, I don't think we want to do either.
> like "A" matches "a" in case insensitive mode),
It doesn't for me. If I type C-s A, it only matches the capital “A”.
Whereas if I type C-s a it matches both “a” and “A”. The same happens
during query-replace and other commands. That's a feature, not a flaw.
If the user explicitly typed out “á”, they probably don't want to
match “a” (or they would have just typed “a” in the first place).

Thanks, I was meaning to look into how to make it toggleable. Will
that snippet make it ON by default? If not, how could I do that?
