Properties use ICU for Unicode V11.0; the beta properties support Unicode V12.0β. For more information, see Unicode Utilities Beta.

Input With this demo, you can supply an Input string and see the combinations that are confusable with it, using data collected by the Unicode consortium. You can also try different restrictions, using characters valid in different approaches to international domain names. For more info, see Data below.

Data

Confusable characters are those that may be confused with others (in some common UI fonts), such as the Latin letter "o" and the Greek letter omicron "ο". Fonts make a difference: for example, the Hebrew character "ס" looks confusingly similar to "o" in some fonts (such as Arial Hebrew), but not in others. See also unaccented Latin Characters..

The data for confusables and restrictions is from UTS39. You can suggest additions or changes to the Unicode data for future versions of that standard.

For more information on the use of the data, see proposed updates Unicode Security Mechanisms and Unicode Security Considerations.

The restrictions are purely on a character level. For a more detailed view, see idna.

Caveats

The Unicode data is designed for testing, not enumerating, so not all combinations are generated in this demo; In particular, where a character is confusable with a sequence, not all combinations are generated.



Fonts and Display. If you don't have a good set of Unicode fonts (and modern browser), you may not be able to read some of the characters. Some suggested fonts that you can add for coverage are: Noto Fonts site, Unicode Fonts for Ancient Scripts, Large, multi-script Unicode fonts. See also: Unicode Display Problems.
