If you have the possibility of only paying attention to the base
character (if the machinery is in place) then there's no reason to
fold "á" into "a´" (folding 1 char into many).

Just fold everything into "a". Then (by only paying attention to the
base character) "á" and "á" will match, because "á" folds into "a"
which is the base character of "á".
