get_page_by_title with an apostrophe in variable

by

Title Hello world!@#$%^*(),.;:\ will work but any title you enter containing ' " < > & characters won’t work because in $content variable you have escaped HTML entities so Mal’s Post becomes Mal&#8217;s Post.

To bypass it you can use sanitize_title function along with get_page_by_path.

function shortcode_equipment($atts, $content = null) {
   $path = sanitize_title($content);

   $equipment = get_page_by_path( $path, OBJECT, 'equipment');

Rest of code works as before.
