Trouble with php 'if exists' syntax

I need to create an if statement for the nbsp (space). 

<?php echo get_post_meta($post->ID, 'the_term', true); echo '&nbsp;'; ?>

This is at the front of a line:

<h2><?php echo get_post_meta($post->ID, 'the_term', true); echo '&nbsp;'; ?>Example

If the term exists, then it'll show 'Term Example'. If not, I need to show 'Example'. But right now, without an if, I get ' Example'. Note the ugly space.

I think I'd done this before, using this:

<?php if (post_custom('the_term')) {
echo get_post_meta($post->ID, 'the_term', true); echo '&nbsp;';
} else {
echo '';
?>

... but it's not working. Server error.

I also tried this:

<?php $the_term_check = get_post_meta($post->ID, 'the_term', true);
if (!empty($the_term_check))
echo '<h2>'; echo get_post_meta($post->ID, 'the_term', true); echo ' Example'</h2>';
if (empty($the_term_check))
echo'<h2>Example</h2>';
?>

Still not it. This one echos 'Example' twice -- and one of them doesn't even have the right HTML markup.

Either plain PHP or WordPress-specific code would work, as this is pulling the custom meta from a custom post type -- if it exists.

Any ideas?

You are missing a closing brace for else { echo '';

Then this echo ' Example'</h2>' there is one quote too many after "Example".

Rewrites

<?php if (post_custom('the_term')) {
echo get_post_meta($post->ID, 'the_term', true); echo '&nbsp;';
} else {
echo '';
} // added missing brace
?>

and

<?php $the_term_check = get_post_meta($post->ID, 'the_term', true);
if (!empty($the_term_check))
echo '<h2>'; echo get_post_meta($post->ID, 'the_term', true); echo ' Example</h2>';
if (empty($the_term_check))
echo'<h2>Example</h2>';
?>

or as, and with added braces (it's good practice)

<?php 
$the_term_check = get_post_meta($post->ID, 'the_term', true);
    if (!empty($the_term_check)){
       echo '<h2>'; echo get_post_meta($post->ID, 'the_term', true); 
       echo ' Example</h2>';
}
    if (empty($the_term_check)){
       echo'<h2>Example</h2>';
}
?>

I think this would work for you.

<h2><?php echo !empty(get_post_meta($post->ID, 'the_term', true)[0]) ? get_post_meta($post->ID, 'the_term', true)[0]."&nbsp;" : ""; ?>Example</h2>
