I posted this on the WP forum, so far to no avail. I'm pretty stuck, so any help is greatly appreciated.

I'm creating a site using WP for my CMS...not necessarily creating an entire theme, but just using WP to allow the customer to make text changes. When I go to display a single post, it gives me all kinds of strange characters. For example, a space bar comes out as . Is there a default WP function to call that will clean this up from SQL? I've searched high and low, and I guess I do not know the correct wording for this problem.

Here's what I am currently using to display a single post in PHP:

   $post_id = 19;
   $queried_post = get_post($post_id);
   $content = $queried_post->post_content;
   $content = apply_filters('the_content', $content);
   $content = str_replace(']]>', ']]>', $content);
   echo $content;
