The ASCII character | is a solid bar, although some older fonts, such as the PC font, will have it displayed broken in half. If you are working only in ASCII, they are two representations of the same thing, but if you are working in extended character sets, they are different, and only the solid one is the ASCII one. Many keyboard layouts are ASCII only, and show the broken bar (I suppose this might confuse people who are unaware of it if they are not working with only ASCII, but anyways people have also asked where is the lowercase, before, so both of them can be confused by some people).
