|+| and then the equals is the upper and lower border.

It does not exactly mean window but it can resemble a window. The digit 1 can be written as a vertical line and the + can be written to represent the wood dividers for the glass planes. If you put that all together it resembles a window.

    Why don't you go try it? 

Or you can stare at this image. ;-)
