How to replace a ‘different’ – with a ‘normal’ – in PHP?

I’m using WP-property (a wordpress plugin) and am trying to use a variable as link in a template. I’m using the following code:

<a href="<?php echo $property['download1link']; ?>" target="_blank"><?php echo   $property['download1tekst']; ?></a>

However, the link doesn’t work as the ‘-‘ is different. How can I fix this (/replace the – with a normal -)?

Output now (ndash):

Output as it should be:

Thanks.
