Is the “missing Unicode character” box a Unicode character itself, and if so, which one?

Question

When browsing the web in Windows XP, Windows is often unable to render more esoteric unicode characters. When this occurs, it replaces the characters with a small box.

If you’re running Windows XP, the following should render as this box, for example: ︙

Is this box a Unicode character itself?

If so, I was thinking that I could put it in my web pages, and see if other Unicode characters I was attempting to use were the same width as it, in order to check whether the other characters were supported or not.

At least in my computer/browser, the displayed character is not always the same... It's a box with the hexadecimal code point inside. — Álvaro González, Jun 08 '11 at 12:30

It is a Unicode code point. It may represent a single character or be one of the combining points (multiple code points forming a character)

Alrighty. Does that mean I can actually use it in a web page? – Paul D. Waite Jun 08 '11 at 12:28

To detect whether a font supports the character? Apparently yes: http://stackoverflow.com/questions/4635683/detect-browser-character-support-in-javascript – Nemanja Trifunovic Jun 08 '11 at 12:42
