    var i;
    
    // Define a string we want to convert to a buffer:
    str = 'this is a string.';
    
    // Manually convert the string to an array of octets...
    octets = new Array( str.length );
    for ( i = 0; i < str.length; i++ ) {
        octets[ i ] = str.charCodeAt( i ) % 256;
    }
