Yes,
As was previously mentioned—the widget for Tiger called CharacterPal is from
http://www.tacowidgets.com/ . I have it but only find it useful on occasion.
Honestly, I find it way too east just to hit
'Cmd Option t' to bring up the character palette. And what is really useful is using the "Favorites" tab which allows you to drag in all the various characters you have occasion to use from all the various character sets you may have.
It's nice and neat & fast—all in one place.
