## Why another `is-fullwidth-code-point`?

Compare to [is-fullwidth-codepoint](https://github.com/sindresorhus/is-fullwidth-code-point), I'm trying to give a fully accurate implementation of official [Unicode EastAsianWidth specification v11.0](ftp://ftp.unicode.org/Public/11.0.0/ucd/EastAsianWidth.txt).

The code in `src/index.ts` is generated by an internal tool that reflects the contents of the specification range by range.

## Install

```
$ npm install @nxmix/is-full-width
```

[Typescript](https://www.typescriptlang.org) definition file is already included.

## Usage

```js
const isFullwidth = require('is-full-width');

isFullwidth('谢'.codePointAt());
//=> true

isFullwidth('a'.codePointAt());
//=> false
```

## API

### isFullwidth(input)

#### input

Type: `number`

[Code point](https://en.wikipedia.org/wiki/Code_point) of a character.
