International prohibition flag (official name), also known as without symbol , without the , circle-backslash symbol , nay , circle interdictory or universal no , is a red circle with a red diagonal line through it (run from top left to bottom right), really attach a pictogram to indicate something that is not allowed. The banned tags sometimes look all black, where colors are not available.
The Unicode code point for the prohibition is U 20E0 , Combining the Rear Cover Circle (?). This is a combine character, meaning that it appears above the character immediately before that, so putting ? Ã, & amp; # x20E0; Ã,? Ã, & amp; # x20E0; should show the eighth note in the prohibition, followed by the infinity symbol inside the ban sign :? ? A? ? A:; It also appears in Webdings and Wingdings 2 fonts.
There are also prohibited sign emoji located at U 1F6AB NO ENTRY SIGN (?), Which are not combined with anything.
According to ISO standards (and also under the UK Statutory Instrument), the red area should take at least 35 percent of the total marking area within the outer circumference of the "ban sign". Therefore, 35 percent of everything inside the outer edge "no symbol" should be the symbol. In addition, for the print marks under UK rules, the width of "no symbols" is set at 80 percent of the height of the printed area.

Usage
The "ban" symbol is used on traffic signs, so drivers can interpret traffic laws quickly while driving. As an example:
- No left turn or No turn right
- No U-rounds
- No parking (English) or No estacionarse (Spanish)
Sometimes symbols are used to warn drivers who do not drive a motor vehicle danger or ban:
- No jumps
- No bikes
- No hikers
By analogy, a sign is used in public places to refer to illegal acts that should not be done with traffic:
- Do not smoke (with cigarette symbol on)
- or Do not throw away any junk (with the symbol of someone littering or dumping the garbage)
- or No swimming (with water swimmer symbols below)
It is also used in mailed packages and sealed merchandise boxes sold in stores. Using graphic symbols is useful when items must be handled by people who may not all understand the same language. As an example:
- May be deleted; do not drop
- Keep away from the magnetic field
In product documentation, this may be accompanied by an image of a product that is being threatened by illicit goods: for example, a cartoon from a floppy disk that is being threatened by a horseshoe magnet.
It also applies to clothing, linen, and other household products to show care, maintenance or cleaning of goods. For example:
- Do not iron
Also, many companies use "ban signs" when describing the services they offer, e.g. insignia of insect spray brand that shows "sign of prohibition" on a mosquito. The Ghostbusters logo is a fictitious example of this, though it uses a mirror image of a symbol without the ISO 3864-1 version.

International standard
While the "ban sign" has been used extensively in advertisements and promotions that now many design variations (eg, reversed from left to right or vary in color) are acknowledged publicly and deemed acceptable, it is still governed by local and international standards. The standard definition of the absent symbol comes from the International Organization for Standardization.
In 2002, ISO 3864-1 was published (the first revised standard issued in 1984). Introduction includes the language on the need to use as few words as possible to convey information.
ISO 3864-1 establishes rules for the colors and safety marks, and controls the merging of text based on the visibility and size of the mark. The range of colors and shapes defined in this standard for "ban symbols" or "no symbols" is defined as "the circle of bans (red ribbon with red slashes from the top left to bottom right) above the black graphic symbol."
Since these standards are not published freely and many publicly visible examples are different from the standard, many public symbols and marks that use them are not strictly based on official standards, but on improper copy or interpretation of the marks or symbols seen by each - artist's chart. This has led to a variety of colors and dimensions. The most common variations seen are bright reds of those specified in standards and widths that are much thinner for lines and slashes, or about exact dimensions but use the same width for slashes as circles (the standard specifies the 80% width as wide as the circle). For example, compare Image: No smoking symbol.png (unsuitable representation) with Image: ProhibitionSign.svg (representation drawn using ISO standard).
Variant
In contrast, the blue circle without a line through it, used as the Mandatory Action Symbol, indicates that the activity represented in the circle is mandatory, and must be executed.
Circles with red borders and no slashes are used under the Vienna Convention on Road Signs and Signals to indicate "No access to vehicles with the following characteristics" such as height, width, mass or speed. In accordance with the European Treaty on the Vienna Convention, an oblique bar shall not be used for any sign other than a sign indicating no turns. The alternate use for a circle abutting red is as a Mandatory Action Symbol B.
The green circle without slashes is sometimes used to mean that something is explicitly allowed, where it may be assumed to be forbidden, for example at a junction where a reversal is allowed.
