# string-length |

|
|
> Get the real length of a string - by correctly counting astral symbols and ignoring [ansi escape codes](https://github.com/sindresorhus/strip-ansi) |
|
|
|
`String#length` erroneously counts [astral symbols](https://web.archive.org/web/20150721114550/http://www.tlg.uci.edu/~opoudjis/unicode/unicode_astral.html) as two characters. |
|
|
|
## Install |
|
|
|
``` |
|
$ npm install string-length |
|
``` |
|
|
|
## Usage |
|
|
|
```js |
|
const stringLength = require('string-length'); |
|
|
|
'🐴'.length; |
|
//=> 2 |
|
|
|
stringLength('🐴'); |
|
//=> 1 |
|
|
|
stringLength('\u001B[1municorn\u001B[22m'); |
|
//=> 7 |
|
``` |
