The purpose of having such a logo is to highlight the fact that the web page uses Unicode encoding. There are still millions and millions of people in the world who don't have a clue what Unicode is. Displaying the logo enhances the visibility of Unicode to your web page visitors.
Then maybe that's what the logo should say: 'Unicode encoded'. That states simply and accurately what the logo is intended to communicate.
Attached is mockup with globe+checkmark image hopefuly conveying something along the lines of 'the world speaks Unicode' or 'this website works everywhere'.
Note, I'm a type designer, not a logo designer, so I don't know whether this mockup might look too much like something else out there: it's hardly an innovative idea.
