    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash

```

</section>

<section class="usage">

## Usage

```javascript
var string2buffer = require( '@stdlib/buffer-from-string' );
```

#### string2buffer( str\[, encoding] )

Allocates a [buffer][@stdlib/buffer/ctor] containing a provided `string`.

```javascript
var buf = string2buffer( 'beep boop' );
// returns <Buffer>
```

The default character encoding is `utf8`. To specify an alternative encoding, provide an `encoding` argument.

```javascript
var buf = string2buffer( '7468697320697320612074c3a97374', 'hex' );
// returns <Buffer>
```

The following `encodings` are supported:

-   `utf8` (`utf-8`)
-   `hex`
-   `binary`
-   `ascii`
-   `ucs2` (`ucs-2`)
-   `base64`

## Examples

var randint = require( '@stdlib/random-base-discrete-uniform' );
var string2buffer = require( '@stdlib/buffer-from-string' );

// Create a buffer from a string:
var buf = string2buffer( 'beep boop bop' );
console.log( buf.toString() );

// Generate random strings...
var i;
var j;
for ( i = 0; i < 100; i++ ) {
    j = randint( 0, buf.length );
    if ( randu() < 2/buf.length ) {
        buf[ j ] = 32; // space
    } else {
        buf[ j ] = randint( 97, 122 );
    }
    console.log( buf.toString() );
}
