What about finding "ä" (a 2-character sequence) when looking for "ä", or
finding "å" (1 character) when looking for "å" (2 characters) -- would

Emacs has many features on by default that are not anywhere else, or
weren't when Emacs introduced them.  So I don't think this argument
should guide our decisions.
