wpalchemy metaboxes VS. wordpress wp_editor() for older versions of PHP

editor_meta.php

<div class="my_meta_control">

<?php $mb->the_field('test_editor'); 

$settings = array( 
	'textarea_rows' => '10',
	'media_buttons' => 'false',
	'tabindex' =>2
);


$val =  html_entity_decode($mb->get_the_value()); 
$id = $mb->get_the_name();
wp_editor($val,  $id , $settings );
				
?>
	
</div>

functions.php

<?php

$editor_metabox = new WPAlchemy_MetaBox(array

WPAlchemyeditor_meta.php

<div class="my_meta_control">

<?php $mb->the_field('test_editor'); 

$settings = array( 
	'textarea_rows' => '10',
	'media_buttons' => 'false',
	'tabindex' =>2
);


$val = html_entity_decode($mb->get_the_value(), ENT_QUOTES, 'UTF-8'); 
$id = $mb->get_the_name();
wp_editor($val,  $id , $settings );

</div>

This should work on older versions of php where html_entity_decode does not default to UTF-8
