Using Firefox 2 (I know, I'm stuck with an old OS for the time being), I see a hand with a pointing finger for ☞ which is OK. But what's NOT is, I see a question mark (not a box) for ➚
This makes the links look like
Sitepoint Css Reference ➚
Maybe instead of using unicode for "special" characters that might not be displayed depending on what's available to the browser, you could use a small image instead?
