## Install

```js

npm install -S utf-info

```

## Use

```js

const utfInfo = require( 'utf-info' );

// syntax:

utfInfo( character, encoding );

// character => single Unicode character (string)

// encoding => valid UTF encoding (string) viz. utf-8, utf-16, and utf-32

// examples:

const result = utfInfo( '😊' ); // character `😊`

// const result = utfInfo( '\x41', 'utf-8' ); // '\x41' is ASCII escape character `A`

// const result = utfInfo( '\u0906', 'utf-16' ); // '\u0906' is Unicode escape for character `आ`

/**************

result => {

    character: '😊',

    codePoint: {

        dec: 128522,

        hex: '01F60A',

        bits: 20

    },

    codeUnits: {

        count: '2',

        dec: [55357, 56842],

        binary: ['1101100000111101', '1101111000001010'],

        hex: ['D83D', 'DE0A'],

        escape: { ascii: null, unicode: '\\uD83D\\uDE0A' }

    }

}

**************/

```

## Run test

```

cd /repo/utf-info/

npm run test

fn:utfInfo suit

    ✓ should return 0041 code point for the character A

    ✓ should return 0906 code point for the character आ

    ✓ should return `["D83D", "DE0A"]` UTF-16 code units for the character 😊
