Get a [UTF-16](https://wikipedia.org/wiki/UTF-16)-encoded code point number of a character

```javascript
'A'.charCodeAt(0); //=> 65
codePoint('A'); //=> 65

'嶲'.charCodeAt(0); //=> 55422
codePoint('嶲'); //=> 195060
```

## Installation

### Package managers

#### [npm](https://www.npmjs.com/)

```
npm install code-point
```

#### [Bower](http://bower.io/)

```
bower install code-point
```

### Standalone

[Download the script file directly.](https://raw.githubusercontent.com/shinnn/code-point.js/master/browser.js)

## API

### codePoint(*character*)

*character*: `String`  
Return: `Number`

If it takes a string as an argument, it returns the same result of `character.codePointAt(0)`.

It throws an error if the argument is not a string or the string is empty.

```javascript
codePoint('\udada'); //=> 56026
codePoint('\udada\udfdf'); //=> 814047
```

It works correctly even in ECMAScript <= 5 environments that don't support  [`String.prototype.codePointAt`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String/codePointAt).
