Now there's a thing -- I tried dragging and dropping the Apple symbol into the Character Palette and again it immediately went to the symbol's location, which is where no-one would ever find it:
Unicode -- Private Use Area -- Private Use Characters -- F8F0.
Click on the Font Variation triangle at the bottom and it shows all the available versions, including the outline one where it's available -- in the Lucida Grande font for example. Sadly this application (Safari, presumably) does not support it so I can't reproduce it here.
