Strange characters in text

Did you export and import the database? This has happened to me several times when switching databases. I’ve found the easiest way to fix this is to either download a plugin like “Find Replace” or doing it directly in the MySQL myphpadmin using this query.

UPDATE wp_posts SET post_content = REPLACE ( post_content, ‘text to find here’, ‘text to replace here’);

In your case you would use this.

UPDATE wp_posts SET post_content = REPLACE ( post_content, ‘–’, ”);
