> [Regular expression][mdn-regexp] to match an unpaired [UTF-16][utf-16] surrogate.

<section class="usage">

## Usage

<!-- eslint-disable id-length -->

```javascript
var reUtf16UnpairedSurrogate = require( '@stdlib/regexp/utf16-unpaired-surrogate' );
```

#### reUtf16UnpairedSurrogate()

Returns a [regular expression][mdn-regexp] to match an unpaired [UTF-16][utf-16] surrogate. 

<!-- eslint-disable id-length -->

```javascript
var RE_UTF16_UNPAIRED_SURROGATE = reUtf16UnpairedSurrogate();

var bool = RE_UTF16_UNPAIRED_SURROGATE.test( 'abc\uD800def' );
// returns true
```

#### reUtf16UnpairedSurrogate.REGEXP

[Regular expression][mdn-regexp] to match an unpaired [UTF-16][utf-16] surrogate. 

```javascript
var bool = reUtf16UnpairedSurrogate.REGEXP.test( 'abc\uD800def' );
// returns true
```
