German license plate depicting diagonal gap Unicode 9.0 introduced another method to create a short diagonal stroked form by adding the Variation Selector 1 U+FE00 after the zero, on this browser it produces 0︀. 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.Īs 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. This means that the slashed zero glyph is displayed for U+0030 only- and then always-when a font whose designer chose the option is active.

Since nearly all software requires each base-10 digit to have only a single, unique semantic representation, Unicode defines no code point (other than U+0030) for altering the visual appearance of zero. In Unicode, slashed zero is considered a typographic variation of the Arabic digit zero 0, which is code point U+0030.

See the disambiguation page for the symbol Ø for a comprehensive listing: Ø (disambiguation). The slashed zero has the disadvantage that it can be confused with several other symbols. The reason for their use is unknown, but has been conjectured to be related to themes of 'negation, erasure, and absence'. Slashed zeroes have been used in the Flash-based artwork of Young-Hae Chang Heavy Industries, notably in their 2003 work, Operation Nukorea. Some cartoons depicted computer users talking in binary code with 1s and 0s using a slashed zero for the 0. The use of the slashed zero by many computer systems of the 1970s and 1980s inspired the 1980s space rock band Underground Zerø to use a heavy metal umlaut Scandinavian vowel ø in the band's name and as the band logo on all their album covers (see link below).Īlong with the Westminster, MICR, and OCR-A fonts, the slashed zero became one of the things associated with hacker culture in the 1980s. Additionally, the slashed zero is used in many ASCII graphic sets descended from the default typewheel on the Teletype Model 33. It is used in many Baudot teleprinter applications, specifically the keytop and typepallet that combines 'P' and slashed zero. The result would look very much like a slashed zero. Typists could generate it by first typing either an uppercase 'O' or a zero and then backspace, followed by typing the slash key. In the days of the typewriter, there was no key for the slashed zero. The slashed zero predates computers, and is known to have been used in the twelfth and thirteenth centuries. Slashed zeros are used on New Zealand number plates. Slashed zeroes can also be used on cheques in order to prevent fraud, for example: Changing a 0 to an 8. It also denotes an absence of something (similar to the usage of an ' empty set' character), such as a sign or a symptom. The slashed zero is also used in charting and documenting in the medical and healthcare fields to avoid confusion with the letter 'O'. The slashed zero can be used in stoichiometry to avoid confusion with the symbol for oxygen (capital O). In this usage it was sometimes called communications zero. The slashed zero was used on teleprinter circuits for weather applications. It is used by computer programmers, in recording amateur radio call signs and in military radio, as logs of such contacts tend to contain both letters and numerals. The slashed zero is used in a number of fields in order to avoid confusion with the letter 'O'. Slashed zeroes on a bus stop sign in Portugal, 2020.
