the zero. In the FE-Schrift typeface, used on German car license plates, the zero is rectangular and has an "insinuated" slash: a diagonal crack just beneath the top right curve. Typefaces Typefaces commonly found on personal computers that use the slashed zero include: Terminal in Microsoft's Windows line. Consolas in Microsoft's Windows Vista, Windows 7, Microsoft Office 2007 and Microsoft Visual Studio 2010 Menlo in macOS Monaco in macOS SF Mono in macOS The Fedora Linux distribution ships with a tweaked variant of the Liberation typeface which adds a slash to the zero; this is not present on most other Linux distributions. ProFont Roboto Mono Dotted zero typefaces: The DejaVu family of typefaces has a "DejaVu Sans Mono" variant with a dotted zero. Andalé Mono has a dotted zero. IBM Plex Mono uses a dotted zero. Source Code Pro and its associated typefaces use a dotted zero. Variations Dotted zero The zero with a dot in the center seems to have originated as an option on IBM 3270 display controllers. The dotted zero may appear similar to the Greek letter theta (particularly capital theta, Θ), but the two have different glyphs. In raster fonts, the theta usually has a horizontal line connecting, or nearly touching, the sides of an O; while the dotted zero simply has a dot in the middle. However, on a low-definition display, such a form can be confused with a numeral 8. In some fonts the IPA letter for a bilabial click (ʘ) looks similar to the dotted zero. Alternatively, the dot can become a vertical trace, for example by adding a "combining short vertical line overlay" (U+20D3). It may be coded as 0&#x20D3; giving 0⃓. Slashed letter 'O' IBM (and a few other early mainframe makers) used a convention in which the letter O had a slash and the digit 0 did not. This is even more problematic for Danes, Faroese, and Norwegians because it means two of their letters—the O and slashed O (Ø)—are visually similar. This was later flipped and most mainframe chain or band printers used the opposite convention (letter O printed as is, and digit zero printed with a slash Ø). This was the de facto standard from 1970s to 1990s. However current use of network laser printers that use PC style fonts caused the demise of the slashed zero in most companies – only a few configured laser printers to
