I just added some dashes around those space characters to see if they were different. On Firefox, the en-space, em-space and thin-space are all different widths. The nbsp is larger than a thin-space, but smaller than an en-space, so I assume that is correct. IE6 displays the en-space, em-space and thin-space the same - about the size of an en-space.

I figured that there were probably some fonts that would display the characters better than others. The main reason for posting the files was to make everyone aware that using all of these characters is still problematic and to let them test the characters on different configurations. Proper display depends on the operating system, reader software and font. It is good that most of these do display correctly, so we can feel relatively safe in using most of them.

Edit: I was mistaken about the zwnj and zwj in Firefox. They aren't correct. I get a vertical line and a vertical line with an x at the top. And I noticed that the soft-hyphen displays nothing in both FF and IE6.
