I think it's a question of logic. One writes an o and then puts a ~ on top
of it. On typewriters, they switched this around because of the mechanical
movement of the carriage and nonspacing technology. But for instance a
smart font would take the bounding box

So what? Your answer shows exactly what I said: that ä and à differ only in
the minds of Swedes.
1. Both are used in Swedish texts (2 biljetter à 40 kronor).
2. Both can be represented in the UCS in two ways: ä by 00E4 or 0065 +
0308, and à by 00E0 or 0065 + 0308.
3. à is sorted as a variant of a with a diacritical mark (p. 1 of Norstedts
svensk-engelska ordbok 1994).
4. ä is sorted as a separate letter of the alphabet (p. 855 of Norstedts
svensk-engelska ordbok 1994).
Technically, there is no difference except in Swedish implementation.
