# 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');
