I think what N1ND refers to are characters which look like zeros but 
are not.

Among these are the Set Theory symbol for the Empty Set (Unicode 
0x2205), the slashed O (slashed oh, not slashed zero) that I think is 
found in northern European font (in the Unicode position 0x00d8, whose 
official Unicode name is "Latin Capital letter O with stroke," with the 
lower case at Unicode 0x00f8), the Greek phi (Unicode 0x03a6), etc.

None of these are the same as the real zero which is ASCII 0x30 
(Unicode 0x0030), which in traditional designs are not slashed.  Odder 
still is that even when a zero displays as a slash in some font, it may 
not have the slash when you typologically (instead of geometrically) 
shrink the font -- the Monaco font is often designed this way.
