`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

```sh
npm install string-length
```

## Usage

```js
import stringLength from 'string-length';

'🐴'.length;
//=> 2

stringLength('🐴');
//=> 1

//=> 7
```
