These are specific to Emacs, and should be added.

I'm not at all sure we should compare a and á equal.  It's an
additional feature anyway.  If we do want them to compare equal in
some cases, then yes, you take only the first character of the
decomposition (the so-called "base character").

As I explained, the user can type the decomposed character instead.

Again, this is not necessarily about easier typing, this is about
comparing equivalent text equal.
