The American is how it is supposed to be.

The British one has the "color" changed changed to "colour" due to British spelling of color.

The Spanish one has an upside down semi colon because in Spanish you write questions like this: ¿Is this an example question?

The French one is because the French number system makes absolutely no sense and to say 99 you have to say quatre-vingt-dix-neuf (meaning 4 x 20 + 19).

I hope this helps somehow.
