Doesn't matter where it's encoded. It is to be considered, if you
will pardon the term, as a kind of dingbat, if I understand correctly.

Because it isn't a "logo", is used officially and obligatorily in
government documents in at least two countries, one of which does not
normally use the Arabic script, and it isn't reasonable to expect
people to type it in, especially because of its usual font
representation. Therefore, and also since it will be required in
interchange, it seemed best to add it to the standard. One suspects
that it will be used rather more than the other word-ligatures
encoded already.
