Can we see your front-page.php code as its possibly part of the html as mine uses a different template and it only has one dash.
It’s in here bb-includes/functions.bb-template.php (line 680):
function forum_description( $args = null ) {
if ( is_numeric($args) )
$args = array( 'id' => $args );
elseif ( $args && is_string($args) && false === strpos($args, '=') )
$args = array( 'before' => $args );
$defaults = array( 'id' => 0, 'before' => ' – ', 'after' => '' );
$args = wp_parse_args( $args, $defaults );
if ( $desc = apply_filters( 'forum_description', get_forum_description( $args['id'] ), $args['id'], $args ) )
echo $args['before'] . $desc . $args['after'];
}
So you could probably whip up some function to override it.
You both have one dash, most likely, but different fonts

Oh, how dumb of me. I just needed to remove &#8212 ; from the line.
EDIT: Apparently the code above keeps changing even between backticks.
Use this:
<?php forum_description( array( 'before' => false, 'after' => false ) ); ?>
