Maybe the default is wrong:
a should catch only a (and not aAàá etc.)
a case modifier would allow a to catch aA
and a diacritic modifier would allow a to catch aàá etc.
the free case and diacritic modifier can be combined so that a can catch aAàÀáÁ 
etc.

ie, the default it to catch *exactly* what the user types.
