the band's name and as the band logo on all their album covers (see link below). Along with the Westminster, MICR, and OCR-A fonts, the slashed zero became one of the things associated with hacker culture in the 1980s. Some cartoons depicted computer users talking in binary code with 1s and 0s using a slashed zero for the 0. Slashed zeroes have been used in the Flash-based artwork of Young-Hae Chang Heavy Industries, notably in their 2003 work, Operation Nukorea. The reason for their use is unknown, but has been conjectured to be related to themes of 'negation, erasure, and absence'. Similar symbols The slashed zero has the disadvantage that it can be confused with several other symbols. See the disambiguation page for the symbol Ø for a comprehensive listing: Ø (disambiguation). Representation in Unicode and HTML In Unicode, slashed zero is considered a typographic variation of the Arabic digit zero , which is code point . Since nearly all software requires each base-10 digit to have only a single, unique semantic representation, Unicode defines no code point (other than ) for altering the visual appearance of zero. This means that the slashed zero glyph is displayed for only—and then always—when a font whose designer chose the option is active. Successful display on a particular local system depends on making sure that such a font is available there, either via the system's font files or via font embedding, and also ensuring it is selected. As an explicit visual representation, Unicode supports slashed zero only indirectly, not as a single-character code point, but as two characters are paired in a combining sequence. see Combining solidus below. Unicode 9.0 introduced another method to create a short diagonal stroked form by adding the Variation Selector 1 after the zero, on this browser it produces . Typography In most typographic designs, the slash of a slashed zero usually does not extend past the ellipse. Compare this to the Scandinavian vowel "Ø", the "empty set" symbol "∅" and the diameter symbol ⌀. A convention common on early line printers left zero unornamented but added a tail or hook to the letter-O so that it resembled an inverted Q (like U+213A ℺) or cursive capital letter-O (). In the Fixedsys typeface, the numeral 0 has two internal barbs along the lines of the slash. This appears much like a white "S" within the black borders of
