It's not exactly a rectangle though, the two downward strokes extend slightly past the bottom horizontal stroke.



In handwriting, or calligraphy, it might be rendered like this, in fact:

       2
      --------+
  1 \        /
     \ ---- /
        3
The three strokes not all connected, and the left and right sides tapering downward a bit (exaggerated in the ASCII above).

It seems there are two schools on the relationship between stroke 2 or 3: 2 can extend downward past 3, or 3 can underscore 2.

Maybe it is a missing character after all :) (Oh no, I've been fooled by chrome/freetype/something!)


I see, it is indeed showing a missing character symbol on your computer. The actual character is much more square than that, in addition to the strokes I mentioned. (http://i.imgur.com/s6bW7u0.png)


Yep, that's the missing character glyph - known colloquially as "tofu".


Yes, it is.
